**monomial_value**,
a FORTRAN90 code 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.

a C++ version and
a FORTRAN90 version and
a MATLAB version and
a Python version.
