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.

zlat2c.f - SYNOPSIS
Functions/Subroutines subroutine zlat2c (UPLO, N, A, LDA, SA, LDSA, INFO) ZLAT2C converts a double complex triangular matrix to a complex triangular matrix. Function/Subroutine Documentation subroutine zlat2c (characterUPLO, integerN, complex*16, dimension( lda, * )A, integerLDA, complex, dimension( ldsa, * )SA, integerLDSA, integerINFO) ZLAT2C converts a double complex triangular matrix to a complex triangular matrix. Purpose: ZLAT2C converts a COMPLEX*16 triangular matrix, SA, to a COMPLEX triangular matrix, A. RMAX is the overflow for the SINGLE PRECISION arithmetic ZLAT2C 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: UPLO UPLO is CHARACTER*1 = 'U': A is upper triangular; = 'L': A is lower triangular. N N is INTEGER The number of rows and columns of the matrix A. N >= 0. A A is COMPLEX*16 array, dimension (LDA,N) On entry, the N-by-N triangular coefficient matrix A. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N). SA SA is COMPLEX array, dimension (LDSA,N) Only the UPLO part of SA is referenced. On exit, if INFO=0, the N-by-N coefficient matrix SA; if INFO>0, the content of the UPLO part 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 the UPLO part of SA in exit is unspecified.
