\param[in] M base of the matrix power, should be a square matrix.
\param[in] p exponent of the matrix power, should be an integer or
the same type as the real scalar in \p M.
\param[in] p exponent of the matrix power, should be real.
The matrix power \f$ M^p \f$ is defined as \f$ \exp(p \log(M)) \f$,
where exp denotes the matrix exponential, and log denotes the matrix
logarithm.
The matrix \f$ M \f$ should meet the conditions to be an argument of
matrix logarithm.
matrix logarithm. If \p p is neither an integer nor the real scalar
type of \p M, it is casted into the real scalar type of \p M.
This function computes the matrix logarithm using the
Schur-Pad&eacute; algorithm as implemented by MatrixBase::pow().
