LinearModel

class cuqi.model.LinearModel(forward, adjoint=None, range_geometry=None, domain_geometry=None)

Model based on a Linear forward operator.

Parameters:

• forward (2D ndarray or callable function.) – Forward operator.

• adjoint (2d ndarray or callable function. (optional if matrix is passed as forward))

• range_geometry (integer or cuqi.geometry.Geometry (optional)) – If integer is given a _DefaultGeometry is created with dimension of the integer.

• domain_geometry (integer or cuqi.geometry.Geometry (optional)) – If integer is given a _DefaultGeometry is created with dimension of the integer.

range_geometry

The geometry representing the range.

Type:

cuqi.geometry.Geometry

domain_geometry

The geometry representing the domain.

Type:

cuqi.geometry.Geometry

:meth:`forward` the forward operator.

:meth:`range_dim` the dimension of the range.

:meth:`domain_dim` the dimension of the domain.

:meth:`get_matrix` returns an ndarray with the matrix representing the forward operator.

__init__(forward, adjoint=None, range_geometry=None, domain_geometry=None)
