Save data in for loop
显示 更早的评论
I am new to MATLAB and would like to save all my data from a for loop, however, I it just overwrites my variable and I can only see the last value..
for i=1:50 for j=1:10 out=rand; end end
I need 50x10 matrix of output, but only get one value of out

This video should help:
Eg>
for ii = 1:50
for jj = 1:10
out(ii,jj)=rand(1);
end
end
out will be a matrix of 50*10
Please do not use i,j as variable names as they are inbuilt matlab functions for i and j (complex numbers) Also please read up on how to markup your code in the forum.
