If I'm not screwing up my basic linear algebra (which I often do), I think gsl_linalg_complex_cholesky_decomp (documented at http://www.gnu.org/s/gsl/manual/html_node/Cholesky-Decomposition.html) to factorize a positive definite Hermitian matrix. If you just want to apply the inverse to a vector, then gsl_linalg_complex_cholesky_solve or gsl_linalg_complex_cholesky_svx will accomplish that. If you want to form the actual inverse in memory, then gsl_linalg_complex_cholesky_invert is what you want. - Rhys _______________________________________________ Help-gsl mailing list Help-gsl@gnu.org https://lists.gnu.org/mailman/listinfo/help-gsl
