Hello,

Now I know from what all I have been reading that it is
impossible (just about) to inverse a NxM matrix. but ..
I need to simplify this equation but Rx is a NxM matrix
and Ky is singular (but can be decomposed to RyRy' if needed)

RxRx'Ky \beta - \delta RxRx'RxR' \alpha = 0

is there anyway expressing \beta or \alpha?

please help if possible.
David,

p.s.
