spectrochempy.roll

roll(dataset, pts=0.0, neg=False, **kwargs)[source]

Roll dimensions.

For multidimensional NDDataset, the shift is by default performed on the last dimension.

Parameters

  • dataset (nddataset) – Dataset to be shifted.

  • pts (int) – Number of points toshift.

  • neg (bool) – True to negate the shifted points.

Returns

dataset – Dataset shifted.

Other Parameters

  • dim (str or int, keyword parameter, optional, default=’x’) – Specify on which dimension to apply the shift method. If dim is specified as an integer it is equivalent to the usual axis numpy parameter.

  • inplace (bool, keyword parameter, optional, default=False) – True if we make the transform inplace. If False, the function return a new dataset.
