xlaenv

public void xlaenv(int ispec,
 int nvalue)

This is a port of version 3.1 LAPACK auxiliary routine XLAENV. Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd.. November 2006 .. Scalar Arguments .. INTEGER ISPEC, NVALUE .. Purpose ======= XLAENV sets certain machine- and problem-dependent quantities which will later be retrieved by ILAENV. Arguments ========= ISPEC (input) INTEGER Specifies the parameter to be set in the COMMON array IPARMS. = 1: the optimal blocksize; if this value is 1, an unblocked algorithm will give the best performance. = 2: the minimum block size for which the block routine should be used; if the usable block size is less than this value, an unblocked routine should be used. = 3: the crossover point (in a block routine, for N less than this value, an unblocked routine should be used) = 4: the number of shifts, used in the nonsymmetric eigenvalue routines = 5: the minimum column dimension for blocking to be used; rectangular blocks must have dimension at least k by m, where k is given by ILAENV(2,...) and m by ILAENV(5,...) = 6: the crossover point for the SVD (when reducing an m by n matrix to bidiagonal form, if max(m,n)/min(m,n) exceeds this value, a QR factorization is used first to reduce the matrix to a triangular form) = 7: the number of processors = 8: another crossover point, for the multishift QR and QZ methods for nonsymmetric eigenvalue problems. = 9: maximum size of the subproblems at the bottom of the computation tree in the divide-and-conquer algorithm (used by xGELSD and xGESDD) =10: ieee NaN arithmetic can be trusted not to trap =11: infinity arithmetic can be trusted not to trap NVALUE (input) INTEGER The value of the parameter specified by ISPEC.
