I wouldstart by saying this is not how you define a function.

function fact[a,b,c]=my_fact(x)

That is not valid syntax to define a function in MATLAB.

so how to define it?

[John D'Errico]

You seem to be asking some pretty basic questions. Why not try reading the getting started tutorials?

Even so, rather than my writing how to define a function, you should read what is already written in a great deal of depth, here:
