Workspace Method MatrixPlanck

Description

Sets a matrix to hold blackbody radiation.

The radiation is assumed to be un-polarized and Stokes components
2-4 are zero. Number of Stokes components, that equals the number
of columns in the created matrix, is determined by stokes_dim.
The number of rows in the created matrix equals the length of the
given frequency vector.

The standard definition, in ARTS, of the Planck function is
followed and the unit of the returned data is W/(m3 * Hz * sr).
