sqrt_space¶

gammapy.utils.nddata.sqrt_space(start, stop, num)[source]¶

Return numbers spaced evenly on a square root scale.

This function is similar to numpy.linspace and numpy.logspace.

Parameters:	start : float start is the starting value of the sequence stop : float stop is the final value of the sequence num : int Number of samples to generate.
Returns:	samples : `ndarray` 1D array with a square root scale

Examples

>>> from gammapy.utils.nddata import sqrt_space
>>> sqrt_space(0, 2, 5)
array([0.        , 1.        , 1.41421356, 1.73205081, 2.        ])
