Abstract
An algorithm for computing primary roots of a nonsingular matrix A is presented In particular it computes the principal root of a real matrix having no nonpositive real eigenvalues using real arithmetic The algorithm is based on the Schur decomposition of A and has an order of complexity lower than the customary Schur based algorithm namely the Smith algorithm
