TEST_MAT
Test Matrices
TEST_MAT
is a FORTRAN90 library which
defines test matrices for which some of the determinant, eigenvalues,
inverse, null vectors, P*L*U factorization or linear system solution
are already known, including the Vandermonde and Wathen matrix.
A wide range of matrix
dimensions, forms and properties are available. These matrices may be
useful in testing an algorithm for correctness on a variety of problems.
Some matrices can be rectangular, with the user specifying
the number of rows and columns. Almost all the matrices can be
made of arbitrary size, with the user specifying the dimension.
Different matrix zero structures are available, including diagonal,
bidiagonal, tridiagonal, pentadiagonal, banded, upper and lower
triangular, and Hessenberg.
Different matrix symmetry patterns are available, including
symmetric, antisymmetric, persymmetric, circulant, Toeplitz, and
Hankel.
Matrices are available with known inverses, condition numbers,
determinants, rank, eigenvalues, and characteristic polynomials. Other
matrix properties include positive definiteness, positivity, zero/one,
and adjacency matrices.
Some matrices come from a MATLAB M file collection developed by
Nicholas Higham, Department of Mathematics, University of Manchester.
An earlier version of the collection is available, again as MATLAB
M files, in ACM TOMS Algorithm 694, in the TOMS directory of
the NETLIB web site.
Some matrices are available at
http://math.nist.gov,
the Matrix Market web site.
