+/* Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd.. */
+/* January 2007 */
+
+/* .. Scalar Arguments .. */
+/* .. */
+
+/* Purpose */
+/* ======= */
+
+/* ILAENV is called from the LAPACK routines to choose problem-dependent */
+/* parameters for the local environment. See ISPEC for a description of */
+/* the parameters. */
+
+/* ILAENV returns an INTEGER */
+/* if ILAENV >= 0: ILAENV returns the value of the parameter specified by ISPEC */
+/* if ILAENV < 0: if ILAENV = -k, the k-th argument had an illegal value. */
+
+/* This version provides a set of parameters which should give good, */
+/* but not optimal, performance on many of the currently available */
+/* computers. Users are encouraged to modify this subroutine to set */
+/* the tuning parameters for their particular machine using the option */
+/* and problem size information in the arguments. */
+
+/* This routine will not function correctly if it is converted to all */
+/* lower case. Converting it to all upper case is allowed. */
+
+/* Arguments */
+/* ========= */
+
+/* ISPEC (input) INTEGER */
+/* Specifies the parameter to be returned as the value of */
+/* ILAENV. */
+/* = 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 (DEPRECATED) */
+/* = 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: the crossover point for the multishift QR method */
+/* for nonsymmetric eigenvalue problems (DEPRECATED) */
+/* = 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 */
+/* 12 <= ISPEC <= 16: */
+/* xHSEQR or one of its subroutines, */
+/* see IPARMQ for detailed explanation */
+
+/* NAME (input) CHARACTER*(*) */
+/* The name of the calling subroutine, in either upper case or */
+/* lower case. */
+
+/* OPTS (input) CHARACTER*(*) */
+/* The character options to the subroutine NAME, concatenated */
+/* into a single character string. For example, UPLO = 'U', */
+/* TRANS = 'T', and DIAG = 'N' for a triangular routine would */
+/* be specified as OPTS = 'UTN'. */
+
+/* N1 (input) INTEGER */
+/* N2 (input) INTEGER */
+/* N3 (input) INTEGER */
+/* N4 (input) INTEGER */
+/* Problem dimensions for the subroutine NAME; these may not all */
+/* be required. */
+
+/* Further Details */
+/* =============== */
+
+/* The following conventions have been used when calling ILAENV from the */
+/* LAPACK routines: */
+/* 1) OPTS is a concatenation of all of the character options to */
+/* subroutine NAME, in the same order that they appear in the */
+/* argument list for NAME, even if they are not used in determining */
+/* the value of the parameter specified by ISPEC. */
+/* 2) The problem dimensions N1, N2, N3, N4 are specified in the order */
+/* that they appear in the argument list for NAME. N1 is used */
+/* first, N2 second, and so on, and unused problem dimensions are */
+/* passed a value of -1. */
+/* 3) The parameter value returned by ILAENV is checked for validity in */
+/* the calling subroutine. For example, ILAENV is used to retrieve */
+/* the optimal blocksize for STRTRI as follows: */
+
+/* NB = ILAENV( 1, 'STRTRI', UPLO // DIAG, N, -1, -1, -1 ) */
+/* IF( NB.LE.1 ) NB = MAX( 1, N ) */
