MPOWER (^) is not fully supported for integer classes. Both arguments must be scalar. To operate on each element of the matrix individually, use POWER (.^) for elementwise power. Arguments must be 2-D. To operate on each element of the matrix individually, use POWER (.^) for elementwise power. Principal matrix power is not defined for matrix with negative real eigenvalues. A non-principal matrix power is returned. Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power is a scalar. To operate on each element of the matrix individually, use POWER (.^) for elementwise power. MPOWER (^) is not supported for one sparse argument and one single argument. Maximum number of matrix square roots exceeded. Results may be inaccurate. Matrix power may not exist for singular matrix.
