Sum repetition in matrices

Hi everyone,

Suppose I have matrix d1, d2, d3, d4, d5:

d1 = [0 0 0 1;0 0 0 0]; % input data
d2 = [0 0 0 0;1 0 0 0]; % input data
d3 = [0 1 0 0;0 0 0 0]; % input data
d4 = [0 0 0 0;1 0 0 0]; % input data
d5 = [0 0 0 0;0 0 1 0]; % input data

and matrix c:

c = [10 12 14 5;1 4 9 15];

Then I want matrix m to be:

m1=c+d1
m2=c+d1+d2 % In other words, in each iteration, the new matrix d should be summed with previous one (same for rest of calculation)
m3=c+d1+d2+d3 
m4=c+d1+d2+d3+d4 
m5=c+d1+d2+d3+d4+d5

Can anyone please help me?

Note: matrix d is generated with another loop automatically which is dependent to output of matrix m (sum(sum(m)).

What's wrong with that way? Why do you need a loop?

Actually, I have over than 10,000 of matrix "d", and each of them will be calculated after calculation each matrix "m" (sort of convergence problem).

This works:

d(:,:,1) = [0 0 0 1;0 0 0 0];
d(:,:,2) = [0 0 0 0;1 0 0 0];
d(:,:,3) = [0 1 0 0;0 0 0 0];
d(:,:,4) = [0 0 0 0;1 0 0 0];
d(:,:,5) = [0 0 0 0;0 0 1 0];

c = [10 12 14 5;1 4 9 15];

m(:,:,1) = c;
for k1 = 2:size(d,3)+1
    m(:,:,k1) = m(:,:,k1-1) + d(:,:,k1-1);
end
m = m(:,:,2:end)            % Result for ‘m’

Thanks Star. It was great!

My pleasure!
