Semi-orthogonal matrix

WebOrthogonal matrices as transformations. Another way to interpret orthogonal and semi-orthogonal matrices is to view them as a transformation from one vector space to another (via matrix multiplication). So if U ∈Rn×r is semi-orthogonal, we think of the map U : Rr →Rn obtained via matrix multiplication. WebMar 28, 2012 · The determinant of an orthogonal matrix is either 1 or –1. Geometrically, an othogonal matrix is a rotation, a reflection, or a composition of the two. G. Stewart (1980) developed an algorithm that generates random orthogonal matrices …
