leading eigenvector or principal axis will be measured first.
Similarly, all the remaining h 1 basis vectors (orthonormal
to the previously measured basis vectors) will be measured
one by one in a reducing order of dominance. The
previously measured (p 1)th basis vectors will be utilized
for finding the pth basis vector. The algorithm for pth basis
vector will converge when the new and old values up point
in the same direction i.e. uþT
p up 1 (where uþp
is the new
value of up). It is usually economical to use a finite tolerance
error to satisfy convergence criteria
