TEST_EIGEN is a Python library which generates eigenvalue tests.
The current version of the code can only generate a symmetric matrix with eigenvalues distributed according to a normal distribution whose mean and standard deviation are specified by the user in R8SYMM_GEN.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
TEST_EIGEN is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version and a Python version.
JACOBI_EIGENVALUE, a Python library which implements the Jacobi iteration for the iterative determination of the eigenvalues and eigenvectors of a real symmetric matrix.
TEST_MAT, a Python library which defines test matrices.
