MATLAB: Compare elements from two matrix.

Question

Hi!

I want to compare elements for two matrix and then create another matrix with maximal element (comparing abs(x1) i abs(x2), not x1 i x2).

I wrote this:

But maybe it's possible to do it quicker and more efficient?

for i = 1:numel(x1) 
   if (abs(x1(i)) > abs(x2(i)))
       x(i) = x2(i); 
   else 
       x(i) = x1(i);
   end 
end 

Answer 1

How about this?

x = x1;
idx = abs(x1) < abs(x2);
x(idx) = x2(idx);
