spectrochempy.roll

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

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.
