numpy.ma.ptp¶
- numpy.ma.ptp(obj, axis=None, out=None, fill_value=None)[source]¶
- Return (maximum - minimum) along the the given dimension (i.e. peak-to-peak value). - Parameters: - axis : {None, int}, optional - Axis along which to find the peaks. If None (default) the flattened array is used. - out : {None, array_like}, optional - Alternative output array in which to place the result. It must have the same shape and buffer length as the expected output but the type will be cast if necessary. - fill_value : {var}, optional - Value used to fill in the masked values. - Returns: - ptp : ndarray. - A new array holding the result, unless out was specified, in which case a reference to out is returned.
