[Python]Numpy linspace 的使用方法

numpy.linspace(start, stop, num=50, endpoint=True, retstep=False, dtype=None)

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 output array. If dtype is not given, infer the data type from the other input arguments. New in version 1.9.0. axis : int, optional The axis in the result to store the samples. Relevant only if start or stop are array-like. By default (0), the samples will be along a new axis inserted at the beginning. Use -1 to get an axis at the end. New in version 1.16.0.

Returns:

samples : 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.

實作:

ex:

接著修改一下產生的數字數量
ex:

加入endpoint:
endpoint = True

endpoint = False

加入retstep:

加入dtype:
dtype = float

 dtype = int

最後一個參數 axis 還看不太懂它的作用，之後再查查。
