:fortran_help: " SUBROUTINE ZLAT2C( UPLO, N, A, LDA, SA, LDSA, INFO )\n\n\
* Purpose\n\
* =======\n\
*\n\
* ZLAT2C converts a COMPLEX*16 triangular matrix, SA, to a COMPLEX\n\
* triangular matrix, A.\n\
*\n\
* RMAX is the overflow for the SINGLE PRECISION arithmetic\n\
* ZLAT2C 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\
* UPLO (input) CHARACTER*1\n\
* = 'U': A is upper triangular;\n\
* = 'L': A is lower triangular.\n\
*\n\
* N (input) INTEGER\n\
* The number of rows and columns of the matrix A. N >= 0.\n\
*\n\
* A (input) COMPLEX*16 array, dimension (LDA,N)\n\
* On entry, the N-by-N triangular coefficient matrix A.\n\
*\n\
* LDA (input) INTEGER\n\
* The leading dimension of the array A. LDA >= max(1,N).\n\
*\n\
* SA (output) COMPLEX array, dimension (LDSA,N)\n\
* Only the UPLO part of SA is referenced. On exit, if INFO=0,\n\
* the N-by-N coefficient matrix SA; if INFO>0, the content of\n\
* the UPLO part 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 the UPLO part of SA in exit is unspecified.\n\
