StaticMatrixTransform

class astropy.coordinates.transformations.StaticMatrixTransform(fromsys, tosys, matrix, priority=1, register=True)

Bases: astropy.coordinates.transformations.CoordinateTransform

A coordinate transformation defined as a 3 x 3 cartesian transformation matrix.

Parameters :

fromsys : class

The coordinate system class to start from.

tosys : class

The coordinate system class to transform into.

matrix: array-like :

A 3 x 3 matrix for transforming 3-vectors. In most cases will be unitary (although this is not strictly required).

priority : number

The priority if this transform when finding the shortest coordinate tranform path - large numbers are lower priorities.

Raises :

ValueError :

If the matrix is not 3 x 3
