def sqrt(x):
"""
Compute the square root of x.
For negative input elements, a complex value is returned
(unlike `numpy.sqrt` which returns NaN).
Parameters
----------
x : array_like
The input value(s).
Returns
-------
out : ndarray or scalar
The square root of `x`. If `x` was a scalar, so is `out`,
otherwise an array is returned.

--------
numpy.sqrt
Examples
--------
For real, non-negative inputs this works just like `numpy.sqrt`:
>>> np.lib.scimath.sqrt(1)
1.0
>>> np.lib.scimath.sqrt([1, 4])
array([ 1., 2.])
But it automatically handles negative inputs:
>>> np.lib.scimath.sqrt(-1)
(0.0+1.0j)
>>> np.lib.scimath.sqrt([-1,4])
array([ 0.+1.j, 2.+0.j])
