How to solve a simple if loop

Asked by Patty Oikawa on 15 Dec 2012

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?

There is no such thing as an IF loop.
IF statements do not filter elements out of an array.
MATLAB does not use a THEN keyword.

Use this instead:

Theta = min(Theta,.59);

You could also do it this way:

Theta(Theta>.59) = .59;

4. Assignment statements cannot be with ().
