clag2z.f(3) LAPACK clag2z.f(3) NAME
clag2z.f - SYNOPSIS
Functions/Subroutines subroutine clag2z (M, N, SA, LDSA, A, LDA, INFO) CLAG2Z converts a complex single precision matrix to a complex double precision matrix. Function/Subroutine Documentation subroutine clag2z (integerM, integerN, complex, dimension( ldsa, * )SA, integerLDSA, complex*16, dimension( lda, * )A, integerLDA, integerINFO) CLAG2Z converts a complex single precision matrix to a complex double precision matrix. Purpose: CLAG2Z converts a COMPLEX matrix, SA, to a COMPLEX*16 matrix, A. Note that while it is possible to overflow while converting from double to single, it is not possible to overflow when converting from single to double. This is an auxiliary routine so there is no argument checking. Parameters: M M is INTEGER The number of lines of the matrix A. M >= 0. N N is INTEGER The number of columns of the matrix A. N >= 0. SA SA is COMPLEX array, dimension (LDSA,N) On entry, the M-by-N coefficient matrix SA. LDSA LDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M). A A is COMPLEX*16 array, dimension (LDA,N) On exit, the M-by-N coefficient matrix A. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M). INFO INFO is INTEGER = 0: successful exit Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. Date: September 2012 Definition at line 104 of file clag2z.f.

zlag2c.f(3) LAPACK zlag2c.f(3) NAME
zlag2c.f - SYNOPSIS
Functions/Subroutines subroutine zlag2c (M, N, A, LDA, SA, LDSA, INFO) ZLAG2C converts a complex double precision matrix to a complex single precision matrix. Function/Subroutine Documentation subroutine zlag2c (integerM, integerN, complex*16, dimension( lda, * )A, integerLDA, complex, dimension( ldsa, * )SA, integerLDSA, integerINFO) ZLAG2C converts a complex double precision matrix to a complex single precision matrix. Purpose: ZLAG2C converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A. RMAX is the overflow for the SINGLE PRECISION arithmetic ZLAG2C checks that all the entries of A are between -RMAX and RMAX. If not the convertion is aborted and a flag is raised. This is an auxiliary routine so there is no argument checking. Parameters: M M is INTEGER The number of lines of the matrix A. M >= 0. N N is INTEGER The number of columns of the matrix A. N >= 0. A A is COMPLEX*16 array, dimension (LDA,N) On entry, the M-by-N coefficient matrix A. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M). SA SA is COMPLEX array, dimension (LDSA,N) On exit, if INFO=0, the M-by-N coefficient matrix SA; if INFO>0, the content of SA is unspecified. LDSA LDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M). INFO INFO is INTEGER = 0: successful exit. = 1: an entry of the matrix A is greater than the SINGLE PRECISION overflow threshold, in this case, the content of SA in exit is unspecified.
