Thread Subject: What's the function to compare array elements?

Subject: What's the function to compare array elements?

From: G Iveco

Basically in my array, if an element is lower than 0.5, set it to 0,
above 0.5, set it to 1.

Element by element comparison is too time consuming.

one of the solutions

     vr=rand(1,5);
     v=vr;
     v(v>=.5)=1;
     v(v<.5)=0;
% -or- in this particular case
% v(v~=1)=0;
     [vr;v]
