make_gaussian_pokes

hcipy.mode_basis.make_gaussian_pokes(grid, mu, sigma, cutoff=5)

Make a basis of Gaussians.

Parameters

gridGrid

The grid on which to calculate the mode basis.

muGrid

The centers for each of the Gaussians.

sigmandarray or scalar

The standard deviation of each of the Gaussians. If this is a scalar, this value will be used for all Gaussians.

cutoffscalar or None

The factor of sigma beyond which the Gaussian will be set to zero. The ModeBasis will be sparse to reduce memory usage. If the cutoff is None, there will be no cutoff, and the returned ModeBasis will be dense.

Returns

ModeBasis

The sparse mode basis. If cutoff is None, a dense mode basis will be returned.
