spectrochempy.zeros

zeros(shape, dtype=None, **kwargs)[source]

Return a new NDDataset of given shape and type, filled with zeros.

Parameters:

  • shape (int or sequence of ints) – Shape of the new array, e.g., (2, 3) or 2 .

  • dtype (data-type, optional) – The desired data-type for the array, e.g., numpy.int8 . Default is numpy.float64 .

  • **kwargs – Optional keyword parameters (see Other Parameters).

Returns:

zeros – Array of zeros.

Other Parameters:

  • units (str or ur instance) – Units of the returned object. If not provided, try to copy from the input object.

  • coordset (list or Coordset object) – Coordinates for the returned object. If not provided, try to copy from the input object.
