I want to find the half width full max of a function in matlab. This requires the input arguments to be convertible to floating-point numbers. How do I do this? Is there another way to find FWHM of functions in matlab?

Evaluate the function over the range and use findpeaks

Your question lacks detail. If you have an expression in one or more variables, you can express it as a function (most likely an anonymous function), and then evaluate it as you would any other function. Then, you can use findpeaks or other appropriate functions to get the FWHM data.
See: Function Basics and related documentation linked to on that page, if you are unfamiliar with functions and how to use them.
