# How to solve a simple if loop

I have a variable that ranges between 0.01 and 0.62. I want to find all values of that single vector that exceed 0.59 and make them equal 0.59.
I tried running an if statement and it runs with no errors, but the variable does not change (there are still #s in that variable that are greater than 0.6). the code I have now that doesn't work:
if Theta>0.59
then (Theta=0.59);
end
What am I doing wrong?

1. There is no such thing as an IF loop.
2. IF statements do not filter elements out of an array.
3. MATLAB does not use a THEN keyword.
Theta = min(Theta,.59);
You could also do it this way:
Theta(Theta>.59) = .59;

Good catch, Walter.
