MatrixMapMatrixMap - Map coordinates by multiplying by a matrix

Description:
A MatrixMap is form of MappingMapping which performs a general linear transformation. Each set of input coordinates, regarded as a column-vector, are pre-multiplied by a matrix (whose elements are specified when the MatrixMap is created) to give a new column-vector containing the output coordinates. If appropriate, the inverse transformation may also be performed.
