Synopsis
A SPolynomial<T> contains a set of coefficients; its fundamental operations is evaluating itself at some "x". The number of coefficients is the order of the polynomial plus one, plus an additional 3 as height, center, width.
Example
SPolynomial<Float> pf(3);
pf.setCoefficient(1, 1.0);
pf[5] = 2.0;
pf.setCoefficient(3, 3.0);
pf(2);
Template Type Argument Requirements (T)
-
T should have standard numerical operators. Current implementation only tested for real types (and their AutoDiffs).
Thrown Exceptions
-
Assertion in debug mode if attempt is made to address incorrect coefficients
