TESTING/MATGEN/slarge.f(3) Library Functions Manual NAME TESTING/MATGEN/slarge.f SYNOPSIS Functions/Subroutines subroutine slarge (n, a, lda, iseed, work, info) SLARGE Function/Subroutine Documentation subroutine slarge (integer n, real, dimension( lda, * ) a, integer lda, integer, dimension( 4 ) iseed, real, dimension( * ) work, integer info) SLARGE Purpose: SLARGE pre- and post-multiplies a real general n by n matrix A with a random orthogonal matrix: A = U*D*U'. Parameters N N is INTEGER The order of the matrix A. N >= 0. A A is REAL array, dimension (LDA,N) On entry, the original n by n matrix A. On exit, A is overwritten by U*A*U' for some random orthogonal matrix U. LDA LDA is INTEGER The leading dimension of the array A. LDA >= N. ISEED ISEED is INTEGER array, dimension (4) On entry, the seed of the random number generator; the array elements must be between 0 and 4095, and ISEED(4) must be odd. On exit, the seed is updated. WORK WORK is REAL array, dimension (2*N) INFO INFO is INTEGER = 0: successful exit < 0: if INFO = -i, the i-th argument had an illegal value Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
