Description:
A MatrixMap
is form of
Mapping 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.
Constructor Function

Mapping class.
Attributes
The MatrixMap class does not define any new attributes
beyond those which are applicable to all Mappings.
