TolBlk must be positive. TolTay must be positive. MaxTerms must be positive. MaxSqrt must be positive. Incorrect dimension for Ord. First input must be a single or double square matrix. Infinite derivative. At least one zero eigenvalue is detected in SCHUR(A).\n Matrix A may be singular or badly scaled. Principal matrix logarithm is not defined for A with nonpositive real eigenvalues. A non-principal matrix logarithm is returned. Taylor series failed to converge.\n Possible that function does not have an infinite radius of convergence.\n Try decreasing options.TolBlk or increasing options.TolTay or options.MaxTerms.
