[Numpy-discussion] 'nansqrt' function?

Dear ALL,

In the process of porting an existing (but abandoned) package to the latest
version of Numpy, I stumbled upon a call to a 'numpy.nansqrt' function,
which seems not to exist.

Here is the specific code:

def normTrans(y):
    denom = np.nansqrt(np.nansum(y**2))
    return y/denom

As far as I could find, there is no such 'nansqrt' function in the current
version of Numpy, so I suspect that the above code has not been properly

Am I right, or that function had existed in some past version of Numpy?

Thanks in advance for any comments or suggestions.

Best regards,
