WrightTools.kit.symmetric_sqrt

WrightTools.kit.symmetric_sqrt(x, out=None)

Compute the ‘symmetric’ square root: sign(x) * sqrt(abs(x)).

Parameters

• x (array_like or number) – Input array.

• out (ndarray, None, or tuple of ndarray and None (optional)) – A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.

Returns

Symmetric square root of arr.

Return type

np.ndarray
