In octave:

octave > help sqrt

'sqrt' is a built-in function from the file libinterp/corefcn/mappers.cc

 -- sqrt (X)
     Compute the square root of each element of X.

     If X is negative, a complex result is returned.

     To compute the matrix square root, see *note Linear Algebra::.

     See also: realsqrt, nthroot.
