poly function
Description
The polynomial controlled sources call a poly function that evaluates a polynomial computed from a vector of signals, s1,s2,...,sn, and a vector of coefficients, a0,a1,... using the following formula.
polys1,...,sn,a0,...=a0+a⋅s1+a⋅s2+...+a⋅sn+a⋅s12+a⋅s1s2+a⋅s1s3+...+a⋅s1sn+a⋅s23+a⋅s2s3+a⋅s2s4+...+a⋅s2sn...+a⋅sn2+a⋅s13+a⋅s12s2+a⋅s12s3+...+a⋅s12sn+a⋅s1s22+a⋅s1s2s3+a⋅s1s2s4+...+a⋅s1s2sn+a⋅sn3+...
The coefficients given as a⋅ correspond to sequential locations in the vector of coefficients.
If the vector of coefficients contains only one element, a0, the evaluated polynomial is poly=a0s1, not poly=a0.
