hi every one
I need help with a program to calculate the sum of matrices
If I have a main matrix A and another matrix B and I need to add A+ B = C, then if all of the elements of C are positive, re-combine C+ B and so on, stop when we get a result that is a matrix containing negative elements. finally, we collect all matrices with positive elements.
Regards

What have you done so far? What specific problems are you having with your code?
How do you want to handle potential infinite looping? How do you want your matrices "collected" at the end of the process? Can you provide a small example?

A=[6 5 16; 7 2 5]
B=[1 -1 0;-1 1 0]
A+B=C
if all elements of C are positive, then B+C=D and so on
if one element of C is negative, stop
collect all positive matrices

C(:,:,1)=A+B;
c=2;
while nnz(C(:,:,end)>0)==numel(C(:,:,end))
C(:,:,c)=C(:,:,c-1)+B;
c=c+1;
end
C=C(:,:,1:end-1);
