how to store looping data in a single array or matrix? - matlab

Question

i have a program with nested loop. i want all the values after each loop is completed, to
be stored in a single matrix A or array A.
display should be like
A= value1
value2
value3
etc...
where value1,value2,value3 are answers got at the end of each loop.
here is the program
load('b2.txt');
[M,N]=size(b2);
amp=[1.75,2,2.25,2.5,2.75,3,3.25,3.5,3.75,4];
%defining threshold
m=10501;
for i=10575:75:21000
a=b2(m:i,:);
time=b2(i,2)
t=40;
sum1=0;
sum2=0;
sum3=0;
sum4=0;
sum5=0;
sum6=0;
sum7=0;
sum8=0;
sum9=0;
sum10=0;
for R=1:75
if (a(R,3)>=t) && (a(R,3)<t+5)
sum1=sum1+a(R,1);
elseif (a(R,3)>=t+5) && (a(R,3)<t+10)
sum2=sum2+a(R,1);
elseif (a(R,3)>=t+10) && (a(R,3)<t+15)
sum3=sum3+a(R,1);
elseif (a(R,3)>=t+15) && (a(R,3)<t+20)
sum4=sum4+a(R,1);
elseif (a(R,3)>=t+20) && (a(R,3)<t+25)
sum5=sum5+a(R,1);
elseif (a(R,3)>=t+25) && (a(R,3)<t+30)
sum6=sum6+a(R,1);
elseif (a(R,3)>=t+30) && (a(R,3)<t+35)
sum7=sum7+a(R,1);
elseif (a(R,3)>=t+35) && (a(R,3)<t+40)
sum8=sum8+a(R,1);
elseif (a(R,3)>=t+40) && (a(R,3)<t+45)
sum9=sum9+a(R,1);
elseif (a(R,3)>=t+45) && (a(R,3)<t+50)
sum10=sum10+a(R,1);
end
cumulative_hits=[sum1,sum2,sum3,sum4,sum5,sum6,sum7,sum8,sum9,sum10];
for count=1:10
if cumulative_hits(1,count)<= 0
amplitude(1,count)= 0;
else
amplitude(1,count)=amp(1,count);
end
end
cumulative_hits(cumulative_hits==0)=[];
amplitude(amplitude==0)=[];
y=log10(cumulative_hits);
p=polyfit(amplitude,y,1);
f=polyval(p,amplitude);
end
%disp(p(1,1))
abs(p(1))
m=m+75;
end
need this asap.. thanks :)

Answer 1

You need to provide informations about which variable to store in the resulting array A, but just for your information:
You can always easily append values to it via:
A = [A; new_value];
which works either if new_value is a scalar or if it's a column-vector with identical number of elements like number of columns of A
