hello everybody i'm wondering if it's possible to find the numerical derivative of a piecewise function that i have separately built as a function file in matlbab

What exactly is the derivative of a piecewise function? Does "piecewise" implies a continuous derivative in your problem?

A spline, for example, is piecewise. (Note: there is a spline derivative routine around.)
Piecewise does not necessarily have a smooth derivative.

If you create a vector or array of values by running them through the function, then you can gradient() that vector or array.
