!> !> 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 conversion is aborted and a flag is raised. !> !> This is an auxiliary routine so there is no argument checking. !>
[in] | M | !> M is INTEGER !> The number of lines of the matrix A. M >= 0. !> |
[in] | N | !> N is INTEGER !> The number of columns of the matrix A. N >= 0. !> |
[in] | A | !> A is COMPLEX*16 array, dimension (LDA,N) !> On entry, the M-by-N coefficient matrix A. !> |
[in] | LDA | !> LDA is INTEGER !> The leading dimension of the array A. LDA >= max(1,M). !> |
[out] | 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. !> |
