WebJun 19, 2016 · For a linearly-independent set of vectors, let $M$ be a matrix with these vectors as columns. Then, $\pi=M (M^TM)^ {-1}M^T$ is the matrix of the orthogonal projection onto their span. The orthogonal complement of their span is the kernel of $\pi$, and projection onto this complement is the orthogonal rejection $I-\pi$. Share Cite Follow WebMar 27, 2024 · Vector Projections The vector projectionof a vector onto a given direction has a magnitude equal to the scalar projection. The direction of the vector projectionis the same as the unit vector of that given direction. Recall that when a vector $\ \vec{v}$ is multiplied by a scalar s, its components are given by
