(,,,,,,,,,,,,,) - void spgvd(f_int itype, char jobz, char uplo, f_int n, f_double* ap, f_double* bp, f_double* w, f_double* z, f_int ldz, f_double* work, f_int lwork, f_int* iwork, f_int liwork, f_int info)
Computes all eigenvalues and eigenvectors of a generalized symmetric-definite generalized eigenproblem, Ax= lambda Bx, ABx= lambda x, or BAx= lambda x, where A and B are in packed storage. If eigenvectors are desired, it uses a divide and conquer algorithm.
