Parameters
NNumber of elements in vectors.
XVector X. Modified on return.
incXStride within X. For example, if incX is 7, every 7th element is used.
YVector Y. Modified on return.
incYStride within Y. For example, if incY is 7, every 7th element is used.
PA 5-element vector:
P[0]Flag value that defines the form of matrix H.
-2.0: matrix H contains the identity matrix.
-1.0: matrix H is identical to matrix SH (defined by the remaining values in the vector).
0.0: H[1,2] and H[2,1] are obtained from matrix SH. The remaining values are both 1.0.
1.0: H[1,1] and H[2,2] are obtained from matrix SH. H[1,2] is 1.0. H[2,1] is -1.0.
P[1]Contains SH[1,1].
P[2]Contains SH[2,1].
P[3]Contains SH[1,2].
P[4]Contains SH[2,2].
