CcurveUpdate/MakeSplineBasis [ Functions ]

NAME

    MakeSplineBasis --- make a the spline basis from scratch

FUNCTION

Function to make the spline basis, analogous to makesplinebasis in R. It can be called when the knots, or X values of the curve have changed. This turned out to be rather inefficient, and was replaced by RemakeSplineBasis, but this function remains in the codebase for debugging.

SYNOPSIS

1117 void MakeSplineBasis(curveP theCurve)

INPUTS

    theCurve      a CCurve structure

OUTPUTS

    theCurve, with SplineBasis, SplineBasisCum, SplineBasisInt and SplineBasisExp updated
