How can I solve Ax=B matrix when the command window in matlab mentioned"matrix is badly scaled, singular Rcond 1e-16" something like this
I am using vpa(A), then inv(A) to solve the matrix, but the speed is a bit slow as I need to run for 1e4 times.
What is the difference between using these two methods pinv() and vpa(), inv()?
