Third part in constructing vector v: v-=0.5*(v^T*u)*u, where u is the householder vector.

Parameters

[in,out]	P	packed matrix being constructed
[in,out]	V	matrix V
[out]	q	q
	P_rows	Number of rows of the packed matrix
	V_rows	Number of rows of the matrix V
	k	Index of the householder vector in the block to create
	j	Start column of the block to work on
