WebIt is based on the splitting of a certain linear matrix operator and its argument into strictly lower, diagonal and strictly upper parts, respectively. This allows to unify the perturbation analysis of matrix problems, involving unitary matrices, in which the resulting matrix is upper triangular. Web30 aug. 2016 · First, define the canonical angles and relate them to the projection matrix. The largest canonical angle can be thought of as the distance between the 2 subspaces. However, a single angle doesn’t characterize the positioning of the 2 subspaces. There are as many canonical angles as dimensions in the subspace.
