| ip | - the inner product (IP) context | |
| nds | - number of columns of defl | |
| defl | - first set of vectors | |
| BDS | - B * defl | |
| BDSnorms | - DS_i' * B * DS_i | |
| n | - number of columns of V | |
| which | - logical array indicating columns of V to be used | |
| V | - second set of vectors | |
| BV | - B * V | |
| BVnorms | - V_i' * B * V_i |
| v | - (input) vector to be orthogonalized and (output) result of orthogonalization | |
| Bv | - (input/output) B * v |
| H | - coefficients computed during orthogonalization with V, of size nds+n if norm == NULL, and nds+n+1 otherwise. | |
| norm | - norm of the vector after being orthogonalized | |
| lindep | - flag indicating that refinement did not improve the quality of orthogonalization |
On exit, v0 = [V v]*H, where v0 is the original vector v.
This routine does not normalize the resulting vector.
