eig(A) gives you the eigenvalues. You can count occurrences for algebraic multiplicity. Geometric seems more complicated, but I found this guide by googling your title: https://people.math.carleton.ca/~kcheung/math/notes/MATH1107/wk10/10_algebraic_and_geometric_multiplicities.html

+1. The perfect response to a blanket request for code.

I want matlab code to show me how. ... or example

As with all Matlab commands, you will find that the documentation for the eig command has numerous examples,
