Return the Jones matrix for a linear diattenuator at zero
rotation.
- - d is the diattenuation of the element, i.e.
d=(px-py)/(px+py). Reversibly, transmission in y direction
is (1-d)/(1+d), if transmission in x direction is 1.
- - px is the transmittance in x direction.
- - py is the transmittance in y direction.
- - mode is a string defining the interpretation of
transmittance values: ’intensity’ (default) or ’amplitude’.
Arguments d, px or py can be passed as a scalar
or as a matrix or as a cell array. In the two latter cases, a cell
array M of Jones matrices is returned. The size of M
is set to the maximum of the parameters’ size.
