Math::MatrixReal - Matrix of Reals
|
||
|
|
|
||
|
|
This module includes many important matrix operations and methods:
|
||
|
|
matrix norm, matrix transposition, matrix inverse, determinant of a
|
||
|
|
matrix, order and numerical condition of a matrix, scalar product of
|
||
|
|
vectors, vector product of vectors, vector length, projection of row
|
||
|
|
and column vectors, a comfortable way for reading in a matrix from a
|
||
|
|
file, the keyboard or your code, and many more.
|
||
|
|
|
||
|
|
Systems of linear equations may be solved using an efficient algorithm
|
||
|
|
known as "L-R-decomposition" and several approximative (iterative)
|
||
|
|
methods. The Householder transformation and QL decomposition for the
|
||
|
|
determination of the eigensystem of a real symmetric matrix are also
|
||
|
|
implemented.
|
||
|
|
|
||
|
|
The module also features an implementation of Kleene's algorithm to
|
||
|
|
compute the minimal costs for all paths in a graph with weighted edges
|
||
|
|
(the "weights" being the costs associated with each edge).
