Sum a Matrix within a loop...

Hello, i need help with this... i have a loop with massive data, and i have to improve the efficiency of code..

I have to sum a matrix each iteration for that i created an array. Example:

A=ones(10);

B=(1:1:10);

z=10;

for ii=1:z

C=A+B(ii);

end

My solution was:

A=ones(10);

B=(1:1:10);

z=10;

for ii=1:z

C(:,:,ii)=A+B(ii);

end

D=sum(C,3);

But in this point i have a seriously problem with my hardware (i'm using huge timeseries). Do you have any recommendations for solve this? thank you!

I found the solution, is simpler than i thought. I have to set mi variables,

A=ones(10);

B=(1:1:10);

C=0;

z=10;

for ii=1:z

C=C+A+B(ii);

end

that's all.
