Therefore, since <math>\mathbf{x}</math> is on the column space of <math>\mathbf{A}</math>, the projection matrix, which maps <math>\mathbf{b}</math> onto <math>\mathbf{x}</math> is just <math>\mathbf{A}</math>, or <math>\mathbf{A}\left(\mathbf{A}^\textsf{T}\mathbf{A}\right)^{-1}\mathbf{A}^\textsf{T}</math>.
