linspace(cls, start, stop, num=50, endpoint=True, retstep=False, dtype=None, **kwargs)[source]

Return evenly spaced numbers over a specified interval.

Returns num evenly spaced samples, calculated over the interval [start, stop]. The endpoint of the interval can optionally be excluded.

Parameters:

  • start (array_like) – The starting value of the sequence.

  • stop (array_like) – The end value of the sequence, unless endpoint is set to False. In that case, the sequence consists of all but the last of num + 1 evenly spaced samples, so that stop is excluded. Note that the step size changes when endpoint is False.

  • num (int, optional) – Number of samples to generate. Default is 50. Must be non-negative.

  • endpoint (bool, optional) – If True, stop is the last sample. Otherwise, it is not included. Default is True.

  • retstep (bool, optional) – If True, return (samples, step), where step is the spacing between samples.

  • dtype (dtype, optional) – The type of the array. If dtype is not given, infer the data type from the other input arguments.

  • **kwargs – Keywords argument used when creating the returned object, such as units,

    name, title, …

Returns:

  • linspace (ndarray) – There are num equally spaced samples in the closed interval [start, stop] or the half-open interval [start, stop) (depending on whether endpoint is True or False).

  • step (float, optional) – Only returned if retstep is True Size of spacing between samples.
