-* N (input) INTEGER
-* The number of columns of the matrix A. N >= 0.
-*
-* A (input) COMPLEX*16 array, dimension (LDA,N)
-* On entry, the M-by-N coefficient matrix A.
-*
-* LDA (input) INTEGER
-* The leading dimension of the array A. LDA >= max(1,M).
-*
-* SA (output) 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.
