I have the following problem:
A * Phi = Ax' * Sx + Ay' * Sy
where,
A= Ax' * Ax + Ay' * Ay + Axy' * Axy
and I would like to solve for Phi.
Matrix A is:
1)symmetric
2) [89x89]
3) Rank(A)=88 ( I guess it means that there is no unique solution )
4) Det(A)~=0 ( I guess it means that A is not Singular )
5) A is a Sparse Matrix ( 673 (%8.5) non-zero elements out of 7921 )
How can I find the inverse of A and solve for Phi ?
Thank you
