hi all,

Suppose I have point x = [x0, ..., xn-1] and linear subspace defined by 
Ax=b, A is m x n matrix, b is vector of length m.

What is the best way to find projection of the point x to the
subspace? (Suitable for ill-conditioned cases)

Does anyone have some code (preferably Python or MATLAB)?

Search in google yields 1st place for the article
but the one is unavailable for free.

Thank you in advance,
