Matrix syntax error question

Hello,

I have 2 matrices 500 x 500, A and B.

I want to replace all values within A which are larger than the corresponding values in B WITH the value in B. Hope that makes sense!

I've tried

A(A>B) = B

But i get the error:

"In an assignment A(I) = B, the number of elements in B and I must be the same."

Do I have my syntax wrong? The two matrices are definitely both 500 x 500.

Many thanks,

Luke Blades

index=A>B;
A(index)=B(index);

Yes, what you're missing is a filter on B. As a one liner:

A(A > B) = B(A > B);
