Better Loop Structure to Execute Faster

Hi everyone,

I have a sample loop as below:

tic;
for k=1:3500
    for j=1:10000
    A(j,k)=B(j,k)/(C(j,1)*0.001);
    end
end
toc;

However, this for loop always required 2-3 minutes execution time. Is there any better way to modify this loop in order to shorten the execution time, or it is unavoidable becaused of the large data?

Thank you in advanced.

A = B./C * 1000;

no loop.

Thank you.

Do you mean that I can write in this form:

A = B./(C*0.001);
