Dear All,
Assume the following system of equations:
Ax = b where b is the vector of data of size Nx1, x is the vector of unknown of size Nx1 and A is the matrix of coefficients of size NxN.
The solution is x = pinv(A)*b where pinv(A) is the pseudo inverse of A.
Now if A is of rank N-1, how do we solve of x? i know that infinite solutions exist but is there another approach of solving for x?
Thank you in advance.
