Comments
If expr is a scalar, the result is a scalar which is the natural logarithm of expr. expr must be positive.
If expr is a vector, the result is a vector containing the natural logarithm of each element in expr. Each element of expr must be positive.
If expr is a matrix, the result is a matrix containing the natural logarithm of each element in expr. Each element of expr must be positive.
