evaluateBasisFunctions1 Method

Evaluate basis functions f[], derivatives df[], and optional second derivatives ddf[] at knot value u.

evaluateBasisFunctions1(knotIndex0: number, u: number, f: Float64Array, df: Float64Array, ddf?: Float64Array): boolean

@returns true if and only if output arrays are sufficiently sized

u number knot value for evaluation
f Float64Array preallocated output array of order basis function values
df Float64Array preallocated output array of order basis derivative values
ddf Float64Array optional preallocated output array of order basis second derivative values

Returns - boolean

true if and only if output arrays are sufficiently sized
