`scipy.interpolate._fitpack_impl:bisplev`

source: build-install/usr/lib/python3.14/site-packages/scipy/interpolate/_fitpack_impl.py:627

Signature

def bisplev(x, y, tck, dx = 0, dy = 0)

Summary

Evaluate a bivariate B-spline and its derivatives.

Extended Summary

Return a rank-2 array of spline function values (or spline derivative values) at points given by the cross-product of the rank-1 arrays x and y. In special cases, return an array or just a float if either x or y or both are floats. Based on BISPEV and PARDER from FITPACK.

Parameters

x, y : ndarray: Rank-1 arrays specifying the domain over which to evaluate the spline or its derivative.
tck : tuple: A sequence of length 5 returned by bisplrep containing the knot locations, the coefficients, and the degree of the spline: [tx, ty, c, kx, ky].
dx, dy : int, optional: The orders of the partial derivatives in x and y respectively.

Returns

vals : ndarray: The B-spline or its derivative evaluated over the set formed by the cross-product of x and y.

Notes

See bisplrep to generate the tck representation.

Array API Standard Support

bisplev is not in-scope for support of Python Array API Standard compatible backends other than NumPy.
