polyMod

polyMod(p,m) finds a reduction of the given polynomial with respect to a polynomial modulus.

polyMod(p,m) returns the reduced polynomial of "p" modulo "m".

polyMod(___,tol) uses the value "tol" to compute and distinguish roots to this level of precision. It is recommended to use the default (1e-6) if you do not have Symbolic Math Toolbox.
