desc.transform.Transform.project

Transform.project(y)

Project vector y onto basis.

Equivalent to dotting the transpose of the transform matrix into y, but somewhat more efficient in some cases by using FFT instead of full transform

Parameters:

y (ndarray) – vector to project. Should be of size (self.grid.num_nodes,)

Returns:

b (ndarray) – vector y projected onto basis, shape (self.basis.num_modes)
