Schur

X = POWERM_PADE(A,P) computes the P'th power X of the matrix A, for arbitrary real P and A with no nonpositive real eigenvalues, by the Schur-Pade algorithm. [X,NSQ,M] = POWERM_PADE(A, P) returns the number NSQ of matrix square roots computed and the degree M of the Pade approximant used.If A is... Platforms: Matlab

MAJLE (Weak) Majorization checkS = MAJLE(X,Y) checks if the real part of X is (weakly) majorized by the real part of Y, where X and Y must be numeric (full or sparse) arrays. It returns S=0, if there is no weak majorization of X by Y, S=1, if there is a weak majorization of X by Y, or S=2, if... Platforms: Matlab
