Function Documentation

void psi::cscf::check_rot	(	int	nn,
		int	num_mo,
		double **	cold,
		double **	cnew,
		double *	smat_pac,
		double *	fock_evals,
		int	irrep
	)

check_rot(): Check if a rotation has swapped columns of C

Parameters:

	nn	= number of SO's in an irrep
	num_mo	= number of MO's in an irrep
	cold	= old C matrix
	cnew	= new C matrix
	smat_pac	= S matrix, packed lower triangular
	fock_evals	= Fock matrix eigenvalues
	irrep	= which irrep we're working on (starts from zero)

Returns: none

void psi::cscf::swap_vectors	(	double **	c,
		int	nn,
		int	j,
		int	i
	)

swap_vectors(): Swap two vectors of an SCF coefficient matrix

Parameters:

	C	= SCF coefficient matrix
	nn	= number of rows in C matrix (number of SO's in that irrep)
	j	= one of the columns to swap
	i	= the other column to swap

Returns: none
