pageinv
Description
[
also returns the reciprocal condition number of each page of Y
,RC
] = pageinv(X
)X
. The value
of RC(1,1,i)
is the reciprocal of the condition number of
X(:,:,i)
. If RC(1,1,i) < eps
, then the call
inv(X(:,:,i))
returns a warning that X(:,:,i)
is ill
conditioned. However, pageinv
does not issue a warning for
ill-conditioned inputs.

Results obtained using
pageinv
are numerically equivalent to computing the inverses of each of the same matrices in afor
-loop. However, the two results might differ slightly due to floating-point round-off error.
