:fortran_help: " SUBROUTINE ZLAG2C( M, N, A, LDA, SA, LDSA, INFO )\n\n\
* Purpose\n\
* =======\n\
*\n\
* ZLAG2C converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A.\n\
*\n\
* RMAX is the overflow for the SINGLE PRECISION arithmetic\n\
* ZLAG2C checks that all the entries of A are between -RMAX and\n\
* RMAX. If not the conversion is aborted and a flag is raised.\n\
*\n\
* This is an auxiliary routine so there is no argument checking.\n\
*\n\n\
* Arguments\n\
* =========\n\
*\n\
* M (input) INTEGER\n\
* The number of lines of the matrix A. M >= 0.\n\
*\n\
* N (input) INTEGER\n\
* The number of columns of the matrix A. N >= 0.\n\
*\n\
* A (input) COMPLEX*16 array, dimension (LDA,N)\n\
* On entry, the M-by-N coefficient matrix A.\n\
*\n\
* LDA (input) INTEGER\n\
* The leading dimension of the array A. LDA >= max(1,M).\n\
*\n\
* SA (output) COMPLEX array, dimension (LDSA,N)\n\
* On exit, if INFO=0, the M-by-N coefficient matrix SA; if\n\
* INFO>0, the content of SA is unspecified.\n\
*\n\
* LDSA (input) INTEGER\n\
* The leading dimension of the array SA. LDSA >= max(1,M).\n\
*\n\
* INFO (output) INTEGER\n\
* = 0: successful exit.\n\
* = 1: an entry of the matrix A is greater than the SINGLE\n\
* PRECISION overflow threshold, in this case, the content\n\
* of SA in exit is unspecified.\n\
