Problems 44260 and 44261 work with a monomial representation of multivariate polynomials. This has two parts, a matrix exponents with a row of exponents for each monomial, and a column vector coefficients with a coefficient for each monomial.
It would be nice to define polynomials so they can be multiplied using simple notation:
p = p1*p2;
This can be done by defining a class mPoly with two properties, exponents and coefficients, and two methods: a constructor with the syntax
p = mPoly(exponents, coefficients)
and a method mtimes for multiplying two polynomials. You can assume that the polynomials being multiplied have the same number of variables.
L Y Cao, since you're such a wizard with indices, I'd love to see you solve this without converting to the array form. It would be interesting to compare the approaches.
Andrew Newell, thanks for your advice.

The output of * operator in this solution is a struct, rather than a mPoly object. Nevertheless, the test suite does not check the type of the output.
