WebFeb 19, 2024 · In linear algebra, orthogonal bases have many beautiful properties. For example, matrices consisting of orthogonal column vectors (a. k. a. orthogonal matrices) can be easily inverted by just transposing the matrix. Also, it is easier for example to project vectors on subspaces spanned by vectors that are orthogonal to each other.
