Return evenly spaced values within a given interval.
Values are generated within the half-open interval [start, stop) (in other words, the interval including start but excluding stop). For integer arguments the function is equivalent to the Python built-in range function, but returns a ndarray rather than a list.
Parameters: | start : number, optional
stop : number
step : number, optional
dtype : dtype

---|---|
Returns: | out : ndarray
