Where is my mistake on cumulative sum of 4 matrices?

1 view (last 30 days)
Hi everbody, I have 4 matrices and to find cumulative sum of them, i use this code:
%aa includes 4 matrices (4 line, 101 columns for each line)
for i=1:1:4;
MATLAB gives me one result with this code. How can i generate 4 result with using this code?

No worries.
The code for 4 matrices is much different that for 1 matrix with 4 rows.

My best guess, with the current information as I write this, is that you just need either
cum_sum = cumsum(aa)
cum_sum = cumsum(aa,2)
without using the for loop at all.

If you have one matrix with 4 rows and 101 columns, this works:
cum_sum = cumsum(aa,2);
