User-defined Functions Applied throughout a Script

Hi,

I am attempting to write a Matlab script that uses a user-input (hence general) function, f(x), throughout the script. I thought of using he following:

f = @(x) input('Enter f(x): ')

but then when my (iterative) While loop is executed which contains (f(x)), the prompt pops up after every cycle.

I'd be grateful for any help!

If you have a sufficiently new version of MATLAB,

f = str2func(['@(x)' input('Enter f(x):','s')]);

If your version of MATLAB is a bit older, you need to either inline() or eval() instead of using str2func()
