spectrochempy.logspace¶

logspace(cls, start, stop, num=50, endpoint=True, base=10.0, dtype=None, **kwargs)[source]¶

Return numbers spaced evenly on a log scale.

In linear space, the sequence starts at base ** start (base to the power of start ) and ends with base ** stop (see endpoint below).

Parameters

start (array_like) – base ** start is the starting value of the sequence.
stop (array_like) – base ** stop is the final value of the sequence, unless endpoint is False. In that case, num + 1 values are spaced over the interval in log-space, of which all but the last (a sequence of length num ) are returned.
num (int, optional) – Number of samples to generate. Default is 50.
endpoint (bool, optional) – If true, stop is the last sample. Otherwise, it is not included. Default is True.
base (float, optional) – The base of the log space. The step size between the elements in ln(samples) / ln(base) (or log_base(samples) ) is uniform. Default is 10.0.
dtype (dtype) – The type of the output 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

logspace – num samples, equally spaced on a log scale.
