view mftoolbox/sqrtm_pd.m @ 7:e0817ccb2834 draft
Add square root matrix function file, rename atom at funm_files, modify old toolbox to run it inside GNU Octave.
added funm_files/fun_atom.m
added sqrtm2.m
added toolbox/gecp.m
toolbox/see.m: comment wrong call to subplot
toolbox/tmtdemo.m: add a cast to double, as eig does not admit bool matrix input
removed funm_files/funm_atom.m

function [X,k] = sqrtm_pd(A) %SQRTM_PD Square root of positive definite matrix via polar decomposition. % [X,K] = SQRT_PD(A) computes the Hermitian positive definite % square root X of the Hermitian positive definite matrix A. % It computes the Hermitian polar factor of the Cholesky factor of A. % K is the number of Newton polar iterations used. R = chol(A); [U,H,k] = polar_newton(R); X = H;
