Thread: Matlab, calling function handles in an mfile

Hey all

Suppse i hav a matlab M-fle which is something like
function x = function_name(a,b)
y = f(x)
...

this means that when i want to do the operation associated with function_name, i have to go into the m-file to change y = f(x) for whatever my y function is.

Is there a method by which i could do function x = function_name(y,a,b)
...

therefore y could be defined in the matlab command window, and function name would operate on this y function..

thanks
