Matrix -is:module
Matrix representation suitable for BLAS/LAPACK computations.
Representation of a 2-D affine transformation.
The Matrix type represents a 2x2 transformation matrix along with a
translation vector.
Matrix a1 a2 b1 b2 c1 c2 describes the
transformation of a point with coordinates x,y that is defined by
/ x' \ = / a1 b1 \ / x \ + / c1 \
\ y' / \ a2 b2 / \ y / \ c2 /
or
x' = a1 * x + b1 * y + c1
y' = a2 * x + b2 * y + c2

Type of matrices.
Elements can be of any type. Rows and columns are indexed starting by
1. This means that, if m :: Matrix a and i,j :: Int,
then m ! (i,j) is the element in the i-th row and
j-th column of m.
Memory-managed wrapper type.
Type synonym for a two-dimentsional array, or simply a matrix.
Type of matrices, parameterised on the type of values.
Sparse matrices are implemented as an ordered association list,
mapping coordinates to values.
A transformation matrix. An affine transformation a b c d e f
a b 0
c d 0
e f 1
Row-major matrix supporting efficient slice.
Sparse matrix in coordinate form (row, column, entry) NB: indices are
1-based i.e. A(1,1) is the top-left entry of matrix A
