Matlab syntax error on [~, ...]

Question

I have a working MATLAB code, which works fine on another machine, but when I run it on my own computer it detects the foloowing syntax error:

Expression or statement is incorrect--possibly unbalanced (, {, or [.

This is my code:

    [~,x] = min(A);

I am using Matlab 7.8.0 R2009a 32bit

What version of MATLAB are you using?

The ~ syntax for discarding unwanted return values was only introduced in R2009b.

EDIT: Had 2008a.

I mis-spoke; that syntax was only introduced in R2009b.. So this is indeed the problem. ;)

You have an older version of MATLAB that doesn't recognize the "~" syntax. Change the ~ to "junk" or some other variable name to remind yourself you don't care about the result and the code should run fine.

Or update your MATLAB to the latest version.
