I have such a code;
figure;
for a = 1:length(weekM')
tday_cell = day_cell(week_cell == weekM(a));
for b = 1:length(days)
subplot(length(weekM'), 7, b);
if strcmp(first_entranceM{a, b}, '0')
plot(peaks);
l = [l; 0];
else
tms_cell = ms_cell(week_cell == weekM(a));
ttms_cell = tms_cell(strcmp(tday_cell,days{b}));
l = [l; ttms_cell];
plot(ttms_cell);
end
end
end
I want to plot graphs with subplot function as subplot(3,7,[1:2:3...]). That is, I want to plot graph which has 3 lines, and 7 graphs on each line.
But in my case, it only shows the last line on the first line, and I can't see the remaining graphs.
I'm sure that the data to plot previous graphs are not being lost, but I don't understand why there are missing graphs.
Could you help me to fix this problem?
Your line with the subplot-statement needs to be changed. The first argument is correct. The second argument represents the number of columns and needs to be set to 7 here, since you have 7 days. The last argument is the index of the addressed subplot and needs to be changed in every iteration.
This index can be generated using the sub2ind-function, which calculates the index from the subscripts. The following line can be used instead of yours:
subplot(length(weekM'),7,sub2ind([7,length(weekM')],b,a));

I am trying to draw line with plot in matlab app designer. But i dont know how to create line. I am just redrawing point on new coordinates.
This is my code (functions runs each second) (format of plot is plot(PlotUI,X,Y))
function function2(app)
app.timeCounter = app.timeCounter + 1;
plot(app.UIAxes,app.timeCounter,app.newValDblPublic);
end
I will be thankful for any help.
At the moment you are just plotting the current set of values, if you want to plot the historic values too, you need to keep them in an array and plot the entire array.
%When the GUI is first created, start with one value in the array
app.time_values = [0];
app.y_values = [0];
%Inside your function
function function2(app)
app.time_values(end+1) = app.time_values(end)+1; % Add a new value to the array, 1 greater than the last value
app.y_values(end+1) = app.newValDblPublic;
plot(app.UIAxes,app.time_values,app.y_values);
end
I need one figure with multiple graphs within two loops.
for i=1:length(state)
[block]
for j=1:length(channel)
[block]
subplot(length(state),length(channel)),j)
plot(a,b)% a and b are arrays of doubles.
end
end
I want one figure with size =length(state)*length(channel); for instance I need all the graphs of state(1)within all channels in the first row etc...
But what I get is multiple figures (the length of state).
If I understand well enough here is a way to do it :
figure()
lx = 2;
ly = 3;
for ii = 1:lx
for jj = 1:ly
subplot(lx,ly,ly*(ii-1)+jj)
plot(ii,jj,'o')
end
end
Why ly*(ii-1)+jj?
The syntax of subplot is the following : subplot(nbRows,nbCols,position) and the position is given by an unique index going over all available subplots (see image) which is ly*(ii-1)+jj.
total_Route = zeros(4,4);
tmp = evalin('base', 't'); % i initialise t in the Workspace with the value 1
if(tmp==5)
tmp=1;
end
total_Route(tmp,1) = Distance_Traveled_CM;
total_Route(tmp,2) = Hauptantrieb_Verbrauchte_Energie_CM;
total_Route(tmp,3) = Nebenaggregate_Verbrauch_Real_CM;
total_Route(tmp,4) = t;
Total_Distance_Traveled_CM = sum(total_Route(:,1));
set(handles.edit3, 'string',Total_Distance_Traveled_CM);
Total_Hauptantrieb_Verbrauchte_Energie_CM = sum(total_Route(:,2));
set(handles.edit4, 'string',Total_Hauptantrieb_Verbrauchte_Energie_CM);
Total_Nebenaggregate_Verbrauch_Real_CM = sum(total_Route(:,3));
set(handles.edit5, 'string',Total_Nebenaggregate_Verbrauch_Real_CM);
%% Index
set(handles.edit15, 'string',tmp);
assignin('base', 't', tmp + 1); % with this line i can increment "t" after each pass
guidata(hObject,handles);
Sorry that I did not explain my problem well.
#Sardar_Usama I want to run the loop only once but t should be incremented after each time I click on my Button.
# Sembei Norimaki end is at the end of my codes, have forgotten to write it in my question
#Patrik & #Dennis Jaheruddin let me explain my problem again
I created a Matrix with 4×4 Elements with the Goal to save the results of each my Variable (Total_Distance_Traveled_CM, Total_Hauptantrieb_Verbrauchte_Energie_CM etc...) after each Simulation in the element of my Matrix (See image below).
I want by pressing a button (on my GUI) to get always the sum of each Column.
Example
The first pass: t = 1--> Distance_Traveled(1,1) is 900 the GUI will take through clicking on the Button, the sum of the first column (which is 900+0+0+0) and write it in a static test.
The second pass t = 2--> Distance_traveled(2,1) is 800 the GUI will take the sum of the first column (which is 900+800+0+0) and write it in a static test and the same thing should happen with the other column.
This should continue until t = 4 i.e. until it does the same thing for each column, then it should reset.
I hope, I have explained my problem better this time and I apologize for my bad English.
I appreciate any help.
Based on your code fragment the for loop is only called once.
However, the contents of the for loop are ran for four times. (first for i=1 then for 1=2 etc..)
If you only want to run one of these options the solution is very simple:
i = 1
yourLoopContent
If i is always 0 the first time, and you always want to run it for the current i, it would also be simple:
yourLoopContent
i = i+1;
However if i may not be set properly the first time, things get messy. This is because i is by default defined as the square root of minus 1.
Therefore I would recommend you to use a different letter like t instead. Then you could do this:
if ~exists(t)
t=0;
end
yourLoopContent %Everywhere using t instead of i
t = t+1;
In general you may want to avoid i as an index to stay clear of complex number issues.
I'm not sure if I got your question correctly, but it seems to me that what you look for is a cumulative sum. This can be done either buy summing on 1:t or by using cumsum. I'm not sure why you use a loop, but if this is only for the summing then cumsum can replace that.
Here is some example in your code:
total_Route = zeros(4,4);
% I commented below what is not part of the question
for t = 1:4
total_Route(t,:) = [Distance_Traveled_CM,
Hauptantrieb_Verbrauchte_Energie_CM,
Nebenaggregate_Verbrauch_Real_CM,
t];
% the following line compute the comulative sum from the top of each
% column to every element in it, so cs_total_Route(3,2) is like
% sum(total_Route(1:3,2)):
cs_total_Route = cumsum(total_Route);
Total_Distance_Traveled_CM = cs_total_Route(t,1); % OR sum(total_Route(1:t,1))
% set(handles.edit3, 'string',Total_Distance_Traveled_CM);
Total_Hauptantrieb_Verbrauchte_Energie_CM = cs_total_Route(t,2); % OR sum(total_Route(1:t,2))
% set(handles.edit4, 'string',Total_Hauptantrieb_Verbrauchte_Energie_CM);
Total_Nebenaggregate_Verbrauch_Real_CM = cs_total_Route(t,3); % OR sum(total_Route(1:t,3))
% set(handles.edit5, 'string',Total_Nebenaggregate_Verbrauch_Real_CM);
% set(handles.edit15, 'string',t);
end
And here is a quick look on what cumsum does (with some random numbers for total_Route):
total_Route =
671 4.6012 1.0662 1
840 3.6475 0.58918 2
354 8.6056 2.1313 3
893 4.1362 2.0118 4
cs_total_Route =
671 4.6012 1.0662 1
1511 8.2487 1.6554 3
1865 16.854 3.7867 6
2758 20.991 5.7985 10
Is this what you looked for?
Hi have this code and I don't know how to put the output result with every pixel.I think the output code are not well defined.
EDIT:
I'm going to try to explain the code:
% I have an image
imagen1=imread('recor.tif');
imagen2= double(imagen1);
band1= imagen2(:,:,1);
% I preallocate the result (the image size is 64*89*6)
yvan2= zeros(61,89,1);
% For every pixel of the image, I want to get one result (each one is different).
for i = 1 : nfiles
for j = 1 : nrows
for i = 1:numel(band1)
% I'm doing this because I've to multiply the results of this interpolation with that result a2ldb1y= ldcm_1(:,1). This vector has a length of 2151x1 and I need to muliply the result of the interpolation for (101:267) position on the vector, this is the reason because I'm doing the interpolation since 101 to 267 (also because I don't have that values).
interplan= interp1(van1,man2,t2,'spline');
ma(96) = banda1a(i); % I said 96, because I want to do an interpollation
end
van1= [101 96 266]';
mos1= ma(134);
van2= [0 pos1 0];
t= 101:267;
t2= t';
xi= 101:1:267;
xi2=xi';
interplan= interp1(van1,van2,t2,'spline');
% After this, I 'prepare' the vector.
out=zeros(2151,1)
out(101:267) = interplan;
% And then, I do all this operation (are important for the result)
a2ldb1y= ldcm_1(:,1);
a2ldsum_pesos1= sum(a2ldb1y);
a2l7dout1_a= a2ldb1y.*out;
a2l7dout1_b= a2l7dout1_a./a2ldsum_pesos1;
a2l7dout1_c= sum(a2l7dout1_b);
% And the result a2l7dout1_c I want it for every pixel (the results are different because every pixel has a different value...)
**yvan2(:,:,1)= [a2l7dout1_c];**
end
end
Thanks in advance,
I'm shooting in the dark here, but I think you're looking for:
yvan2(i, j, 1)= a2l7dout1_c;
instead of:
yvan2(:,:,1)= [a2l7dout1_c];
and thus your output should be stored in the variable yvan2 after the loops are done.
P.S
Some issues in your code:
Why do you have two loops using the same iteration variable i? Your calculations are probably incorrect since i is being modified by two for loops.
Why do you even need the second loop? Each iteration overruns the value of ma(134) set by the previous iteration. You can just replace the entire loop with:
ma(134) = banda1a(numel(band1))
You shouldn't be using the names i and j for loop variables. They are already reserved for the imaginary unit (that is, sqrt(-1)), so MATLAB needs extra processing time for name resolution. You'd rather use other loop variable names instead, even ii and jj.
Okay so this sounds easy but no matter how many times I have tried I still cannot get it to plot correctly. I need only 3 lines on the same graph however still have an issue with it.
iO = 2.0e-6;
k = 1.38e-23;
q = 1.602e-19;
for temp_f = [75 100 125]
T = ((5/9)*temp_f-32)+273.15;
vd = -1.0:0.01:0.6;
Id = iO*(exp((q*vd)/(k*T))-1);
plot(vd,Id,'r',vd,Id,'y',vd,Id,'g');
legend('amps at 75 F', 'amps at 100 F','amps at 125 F');
end;
ylabel('Amps');
xlabel('Volts');
title('Current through diode');
Now I know the plot function that is currently in their isn't working and that some kind of variable needs setup like (vd,Id1,'r',vd,Id2,'y',vd,Id3,'g'); however I really can't grasp the concept of changing it and am seeking help.
You can use the "hold on" function to make it so each plot command plots on the same window as the last.
It would be better to skip the for loop and just do this all in one step though.
iO = 2.0e-6;
k = 1.38e-23;
q = 1.602e-19;
temp_f = [75 100 125];
T = ((5/9)*temp_f-32)+273.15;
vd = -1.0:0.01:0.6;
% Convert this 1xlength(vd) vector to a 3xlength(vd) vector by copying it down two rows.
vd = repmat(vd,3,1);
% Convert this 1x3 array to a 3x1 array.
T=T';
% and then copy it accross to length(vd) so each row is all the same value from the original T
T=repmat(T,1,length(vd));
%Now we can calculate Id all at once.
Id = iO*(exp((q*vd)./(k*T))-1);
%Then plot each row of the Id matrix as a seperate line. Id(1,:) means 1st row, all columns.
plot(vd,Id(1,:),'r',vd,Id(2,:),'y',vd,Id(3,:),'g');
ylabel('Amps');
xlabel('Volts');
title('Current through diode');
And that should get what you want.
