LDA >= max(1, N). .fi .PP .br \fIRHS\fP .PP .nf RHS is REAL array, dimension (N). On entry, the right hand side vector b. On exit, the solution vector X. .fi .PP .br \fIIPIV\fP .PP .nf IPIV is INTEGER array, dimension (N). The pivot indices; for 1 <= i <= N, row i of the matrix has been interchanged with row IPIV(i). .fi .PP .br \fIJPIV\fP .PP .nf JPIV is INTEGER array, dimension (N). The pivot indices; for 1 <= j <= N, column j of the matrix has been interchanged with column JPIV(j). .fi .PP .br \fISCALE\fP .PP .nf SCALE is REAL On exit, SCALE contains the scale factor. SCALE is chosen 0 <= SCALE <= 1 to prevent owerflow in the solution. .fi .PP .RE .PP \fBAuthor:\fP .RS 4 Univ\&. of Tennessee .PP Univ\&. of California Berkeley .PP Univ\&. of Colorado Denver .PP NAG Ltd\&. .RE .PP \fBDate:\fP .RS 4 September 2012 .RE .PP \fBContributors: \fP .RS 4 Bo Kagstrom and Peter Poromaa, Department of Computing Science, Umea University, S-901 87 Umea, Sweden\&. .RE .PP .PP Definition at line 115 of file sgesc2\&.f\&. .SH "Author" .PP Generated automatically by Doxygen for LAPACK from the source code\&.
