PPSplineF64.ppev(x)

Evaluate an array of x coordinates derivatives on the pp spline.

Repeatedly applies ppev_single(), and is typically used for minor performance gains in chart plotting.

Warning

The x coordinates supplied to this function are treated as float, or are converted to float. Therefore it does not guarantee the preservation of AD sensitivities. If you need to index by x values which are Dual or Dual2, then you should choose to iteratively map the provided methods ppev_single_dual() or ppev_single_dual2() respectively.

Parameters:

x (ndarray of float) – x-axis coordinates.

Return type:

ndarray
