I am working on signal inversion. I am facing a matrix inversion problem. I have a linear system where, the signal and data are known. I am computing the inverse by simple matrix inversion. However, I am appending a vector with both data and signal matrix. I want to compute the inverse without going for simple inversion again. I want an analytical formula of the data coefficient matrix in terms of data, signal, previous coefficient matrix and the appended vector.
Dear Samiran,
Can you restate your question using mathematical expressions?
Attach them as a pdf file.
Regards
Yes, there depends on the size of matrix, depends either two by two, or three by three variables?
@ Samiran,
Concerning your attached file:
Does the operator [X; u ] = Xn*p up*1 ?
No u is appended as the (N+1)-st row of X.
Similarly u is augmented as the (P+1)-st row in S
