Function Documentation

iargmax2_nrm()

idx_t iargmax2_nrm	(	size_t	n,
		idx_t *	x,
		real_t *	y
	)

These functions return the index of the second largest elements in the vector formed by x.y where '.' is element-wise multiplication

Definition at line 93 of file libmetis/util.c.

iargmax_nrm()

idx_t iargmax_nrm	(	size_t	n,
		idx_t *	x,
		real_t *	y
	)

Returns the highest weight index of x[i]*y[i]
