- nlcpy.reciprocal = <ufunc 'nlcpy_reciprocal'>
Computes the element-wise reciprocal of the input.
Input an array or a scalar.
- outndarray or 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.
- wherearray_like, optional
This condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default
out=None, locations within it where the condition is False will remain uninitialized.
For other keyword-only arguments, see the section Optional Keyword Arguments.
A ndarray, containing the reciprocal for each element of x. If x is a scalar, this function returns the result as a 0-dimension ndarray.
This function is not designed to work with integers.
For integer arguments with absolute value larger than 1 the result is always zero because of the way Python handles integer division. For integer zero the result is an overflow.
