Hi ; I have a problem with my function.
I want to learn its highest degree.
My function is like f(r,s) = a*r^2+b*r*s+c*s^3
for example this functions highest degree for s variabla is 3 and highest degree for r variable is 2.
How can I write a command which returns me the highest degree for r or s variable ?
Thank you

How have you tried? No one will serve a code to you on a silver plate.

If you have the function in symbolic form, then you can use coeffs() from the symbolic toolbox.
If you do not have the function in symbolic form, if all you have is a function handle that can be evaluated, then NO, it is not possible to determine the maximum degree.
