MONOMIAL_VALUE\ Evaluate a Monomial in M dimensions {#monomial_value-evaluate-a-monomial-in-m-dimensions align=”center”} ===================================

MONOMIAL_VALUE is a C++ library which evaluates a monomial in M dimensions.

Let X represent a point in M dimensional space, and let E be a vector of M integers. The value of the monomial with exponents E at the point X is

        V(X) = X(1)^E(1) * X(2)^E(2) * ... * X(M)^E(M)

This library supplies a convenient method of evaluating V(X) at multiple points X.

The factor 0.0\^0 might occur if, for some I, we have X(I) = 0.0 and E(I) = 0. In this case, we take the corresponding value to be 1.

The factor 0.0\^E(I) will cause problems if E(I) is negative.
