ARGUMENTS A (input/output) On entry, A contains the entry in the first vector that cor- responds to the element to be annihilated in the second vec- tor. On exit, contains the nonzero element of the rotated vector. B (input) On entry, B contains the entry to be annihilated in the sec- ond vector. Unchanged on exit. C (output) On exit, C and S are the elements of the rotation matrix that will be applied to annihilate B. S (output) On exit, C and S are the elements of the rotation matrix that will be applied to annihilate B. 7 Nov 2015 crotg(3P)
