xnn.cnn.models.spherical.s2_kernel_basis

xnn.cnn.models.spherical.s2_kernel_basis(points, b)

2b conj(Y^l_m) at filter points (beta, alpha): the matrix that turns filter values into the filter spectrum of an S^2 correlation.

Returns:

Real and imaginary parts, each (n_points, b, 2b - 1) in float64.

Return type:

(Tensor, Tensor)

Parameters:

• points (Tensor)

• b (int)
