{sqrt( { {0, 1}, {4, 9} } )} {0, 1}, {2, 3}

Comments

If expr is a scalar, the result is a scalar which is the square root of expr. expr must be non-negative.

If expr is a vector, the result is a vector of the same dimensions containing the square root of each element in expr. Each element of expr must be non-negative.

If expr is a vector, the result is a vector of the same dimensions containing the square root of each element in expr. Each element of expr must be non-negative.
