numpy.unpackbits(myarray, axis=None)
Unpacks elements of a uint8 array into a binary-valued output array.
Each element of myarray
represents a bit-field that should be unpacked into a binary-valued output array. The shape of the output array is either 1-D (if axis
is None) or the same shape as the input array with unpacking done along the axis specified.
Parameters: |
myarray : ndarray, uint8 type Input array. axis : int, optional Unpacks along this axis. |
---|---|
Returns: |
unpacked : ndarray, uint8 type The elements are binary-valued (0 or 1). |
