windows default iconzkcm for Windows Publisher's description

zkcm library is a C++ library for multi-precision complex-number matrix calculations.

zkcm library is a C++ library for multi-precision complex-number matrix calculations. It provides several functionalities including singular value decomposition, tensor product calculation, and tracing-out operations.

What's New in This Release:

В· An output of warning has been implemented in eig_H_dense that calculates eigenvectors of an Hermitian matrix using the inverse iteration. One can get information on which eigenvector has failed to converge in case it has failed, by this warning message.
В· Furthermore, in addition to receiving a warning message in std::cerr, one can get an array of integers indicating which eigenvectors might be possibly wrong. See the reference manual for the new variant of the function diag_H.

В· In previous versions, there was a very rare case that eigenvalues were not sorted well when we have very small eigenvalues and relatively large eigenvalues. This problem has been fixed by adding yet-another sorting at the end of calculation of eigenvalues and corresponding eigenvectors.

System Requirements:

В· Cygwin
Program Release Status: Major Update
Program Install Support: Install and Uninstall
