Parameters

p  Double
Smoothing parameter.
dx  IReadOnlyListDouble
Inverse abscissa difference vector.
y  IReadOnlyListDouble
Ordinate vector.
y1  VectorDouble
On input, a 1st derivative vector with elements y1(lo) and y1(hi) supplied by the user. On output, the 1st derivative vector with elements y1(i), i = lo+1...hi-1, newly calculated.
f  VectorDouble
Working vector.
z  IReadOnlyListDouble
