- Polynomial. mapparms ( ) ¶
Return the mapping parameters.
The returned values define a linear map
off + scl*xthat is applied to the input arguments before the series is evaluated. The map depends on the
window; if the current
domainis equal to the
windowthe resulting map is the identity. If the coefficients of the series instance are to be used by themselves outside this class, then the linear function must be substituted for the
xin the standard representation of the base polynomials.
- off, scl float or complex
The mapping function is defined by
off + scl*x.
If the current domain is the interval
[l1, r1]and the window is
[l2, r2], then the linear mapping function
Lis defined by the equations:
L(l1) = l2 L(r1) = r2
