`scipy.interpolate._bsplines:_make_interp_per_full_matr`

source: /scipy/interpolate/_bsplines.py :1215

Signature

def _make_interp_per_full_matr ( x , y , t , k )

Summary

Returns a solution of a system for B-spline interpolation with periodic boundary conditions. First k - 1 rows of matrix are conditions of periodicity (continuity of k - 1 derivatives at the boundary points). Last n rows are interpolation conditions. RHS is k - 1 zeros and n ordinates in this case.

Parameters

x : 1-D array, shape (n,): Values of x - coordinate of a given set of points.
y : 1-D array, shape (n,): Values of y - coordinate of a given set of points.
t : 1-D array, shape(n+2*k,): Vector of knots.
k : int: The maximum degree of spline

Returns

c : 1-D array, shape (n+k-1,): B-spline coefficients

Notes

t is supposed to be taken on circle.
