I know I'm not connecting something somewhere, so I need your help.
I have made calculations in each formula and now need to add them together - simple, but not. haha
Here is my code:
Group 1 - student
Group 2 - class
Group 3 - StudentWorkList_.Excuse Type (which is divided by Absent and Tardy)
I have to add the Absences and Tardies together, but for every 3 tardies = 1 Absent.
The calculations come out correctly for each one separately, but I can't add the Absence formula + the Tardy to Absent formula.
Creating another formula with Absent + Tardy to Absent does nothing...
Formulas:
Absent:
if GroupName ({StudentWorkList_.Excuse Type}) = "Absent" then Count ({StudentWorkList_.Excuse Type}, {StudentWorkList_.Excuse Type})/76*100
Tardy to Absent:
if GroupName ({StudentWorkList_.Excuse Type}) = "Tardy" then
if Count ({StudentWorkList_.Excuse Type}, {StudentWorkList_.Excuse Type}) = 3 then 1 /76100 else
if Count ({StudentWorkList_.Excuse Type}, {StudentWorkList_.Excuse Type}) = 4 then 1 /76100 else

Create a simple detail level formula called {#Absence_Equivalent} using an expression such as:
IF {StudentWorkList_.Excuse Type}) = "Absent" Then 1
ELSE IF {StudentWorkList_.Excuse Type}) = "Tardy" Then 1/3
ELSE 0
Then, SUM that formula at any grouping or grand total level you wish.
Option 1: Create a formula that divides the sum by 76 -- that seems like the simplest approach. If for some reason you don't want to do that, then:
Option 2: divide the detail level value by 76. For example,
IF {StudentWorkList_.Excuse Type}) = "Absent" Then 1/76
ELSE IF {StudentWorkList_.Excuse Type}) = "Tardy" Then 1/228
ELSE 0

I have 2 inner while loops. Code writes the results to first row on the matrix but when it gets to second row, it just passes the other rows and doesn't fill the columns of the rows. How to solve it? The code and output are like below:
while i <= m-1
i
while a <= m-1
a
den1 = sqrt(((xy{i,j}-xy{a+1,b})^2+(xy{i,j+1}-xy{a+1,b+1})^2 ));
dMat(i,a) = den1;
a = a+1;
end
i = i+1;
end
i = 1
a = 1
a = 2
a = 3
a = 4
a = 5
a = 6
a = 7
a = 8
a = 9
a = 10
a = 11
a = 12
a = 13
a = 14
a = 15
a = 16
a = 17
a = 18
a = 19
a = 20
a = 21
a = 22
a = 23
a = 24
i = 2
i = 3
i = 4
i = 5
i = 6
i = 7
i = 8
i = 9
i = 10
i = 11
i = 12
i = 13
i = 14
i = 15
i = 16
i = 17
i = 18
i = 19
i = 20
i = 21
i = 22
i = 23
i = 24
You have to restart a to a=1 for each iteration. Put it above the while a <= m-1
I need to find the minimum values in each column of matrix "A", and then replace those min values with the values in last row of matrix "B" (which has same number of columns). Like I have these:
>> A = randi(10,10,5)
A =
3 5 9 5 8
7 6 4 10 2
8 4 1 7 4
4 7 2 8 2
7 5 8 7 5
3 7 10 10 1
5 7 8 5 7
8 3 8 2 3
6 10 2 1 10
3 7 6 7 2
>> B = randi(100,3,5)
B =
10 34 66 18 62
99 95 49 54 81
52 1 52 9 95
>> [M,I] = min(A)
M =
3 3 1 1 1
I =
1 8 3 9 6
And I want to replace the values of "M" with "B(end,:), so that:
A(1,1) = B(end,1);
A(8,2) = B(end,2);
A(3,3) = B(end,3);
A(9,4) = B(end,4);
A(6,5) = B(end,5);
I try "A(I) = B(end,:)" and "A(I(1,:)) = B(end,:)" but they do not work! Any ideas how I could do that? My real matrices are huge (1200x100000) so no way to do it by hand!
try this to replace the first min value:
A = [ 3 5 9 5 8;
7 6 4 10 2;
8 4 1 7 4;
4 7 2 8 2;
7 5 8 7 5;
3 7 10 10 1;
5 7 8 5 7;
8 3 8 2 3;
6 10 2 1 10;
3 7 6 7 2];
B =[ 10 34 66 18 62;
99 95 49 54 81;
52 1 52 9 95];
[M,I] = min(A)
A(sub2ind(size(A),I,1:size(A,2)))=B(end,:)
the output will be:
A =
52 5 9 5 8
7 6 4 10 2
8 4 52 7 4
4 7 2 8 2
7 5 8 7 5
3 7 10 10 95
5 7 8 5 7
8 1 8 2 3
6 10 2 9 10
3 7 6 7 2
However, when you have to replace all of the min values, use the code below instead
A = [ 3 5 9 5 8;
7 6 4 10 2;
8 4 1 7 4;
4 7 2 8 2;
7 5 8 7 5;
3 7 10 10 1;
5 7 8 5 7;
8 3 8 2 3;
6 10 2 1 10;
3 7 6 7 2];
B =[ 10 34 66 18 62;
99 95 49 54 81;
52 1 52 9 95];
M = min(A);
for i=1:size(A,2)
A(find(A(:,i) == M(i)),i)=B(end,i);
end;
A
the output is:
A =
52 5 9 5 8
7 6 4 10 2
8 4 52 7 4
4 7 2 8 2
7 5 8 7 5
52 7 10 10 95
5 7 8 5 7
8 1 8 2 3
6 10 2 9 10

You can acces you matrix by a single index, which looks like this:
Indeces =
1 6 11 16
2 7 12 17
3 8 13 18
4 9 14 19
5 10 15 20
Since you get the indeces for each individual column, you just need to increase it by the column number times the height of the matrix.
This should yield the correct result:
A( I + (0 : size(A,2)-1) * size(A,1) ) = B(end,:)
I am making an exclude vector, so that the rows containing any value present in the second column of the matrix user from the exclude list are removed. How do I do that efficiently, without using a for loop to iterate through user for each item in exclude one by one?
My code below does not work:
count=0;
% Just showing how I am constructing `exclude`, to show that it can be long.
% So, manually removing each item from `exclude` is not an option.
% And using a for loop to iterate through each element in `exclude` can be inefficient.
for b=1:size(user_cat,1)
if user_cat(b,4)==0
count=count+1;
exclude(count,1) = user_cat(b,1);
end
end
% This is the important line of focus. You can ignore the previous parts.
user = user(user(:,2)~=exclude(:),:);
The last line gives the following error:
Error using ~=
Matrix dimensions must agree.
So, I am having to use this instead:
for b=1:size(exclude,1)
user = user(user(:,2)~=exclude(b,1),:);
end

Use ismember to find the indices of the second column of user where elements of exclude exist to get the indices of the rows to be removed. Negate these row indices to get the row indices to be kept and use matrix indexing to keep these rows.
user = user(~ismember(user(:,2),exclude),:);
x=[3 1 1 -5 -2 0 1 2 -2 2];
A=[4 2 6; 0 1 -3; -2 5 -2];
B=[-2 3 2; 1 5 5; -3 1 0];
sum=0;
for i=2:3
sum_j=0;
for j=1:2
sum_j=sum_j+A(1,j)*B(j,i);
end
sum=sum+A(2,i)*sum_j;
end
fprintf('(c) %g\n',sum);
>> (c) -32
-32 is a correct answer. However, if I initialize sum_j=0 outside of the the loop, it returns a different value.
sum=0;
sum_j=0;
for i=2:3
for j=1:2
sum_j=sum_j+A(1,j)*B(j,i);
end
sum=sum+A(2,i)*sum_j;
end
fprintf('(c) %g\n',sum);
>> (c) -98
Can anyone explain why this is happening?
In your first code sum_j gets reinitialized in the loop for i and in second code sum_j carry the value in each loop. Here is a simulation of your codes
first code:
sum = 0
i=2:
sum_j = 0
i=2,j=1
sum_j = 0 + 4*3 = 12
i=2,j=2
sum_j = 12 + 2*5 = 22
sum = 0 + 1*22 = 22
i=3
sum_j = 0
i=3,j=1
sum_j = 0 + 4*2 = 8
i=3,j=2
sum_j = 8 + 2*5 = 18
sum = 22 + -3*18 = -32
Second code
sum = 0
sum_j = 0
i=2:
i=2,j=1
sum_j = 0 + 4*3 = 12
i=2,j=2
sum_j = 12 + 2*5 = 22
sum = 0 + 1*22 = 22
i=3
i=3,j=1
sum_j = 22 + 4*2 = 30
i=3,j=2
sum_j = 30 + 2*5 = 40
sum = 22 + -3*40 = -98
I coded the following method to convert a Hex String to a int:
-(long)intFromHexString:(NSString*) string
{
char tempChar;
int temp;
tempChar=[string characterAtIndex:[string length]-1];
temp=strtol(&tempChar, NULL, 16);
NSLog(#"***>%c = %i",tempChar,temp);
return temp;
}
Most of the time it works properly but sometimes it really gets into big trouble like this:

Can anyone tell me what's wrong with my code?
You are passing a pointer to a single character into strtol(), rather than a NUL-terminated string, so strtol() is sometimes reading beyond the character you gave it. (For instance, "1033" is the result of it finding "409", rather than just "4".)
Fix:
-(long)intFromHexString:(NSString*) string
{
char tempChar[2];
int temp;
tempChar[0]=[string characterAtIndex:[string length]-1];
tempChar[1] = 0;
temp=strtol(tempChar, NULL, 16);
NSLog(#"***>%c = %i",tempChar[0],temp);
return temp;
}
