anaflow.tools.special.specialrange

specialrange(val_min, val_max, steps, typ='exp')

Calculation of special point ranges.

Parameters:

• val_min (float) – Starting value.

• val_max (float) – Ending value

• steps (int) – Number of steps.

• typ (str or float, optional) – Setting the kind of range-distribution. One can choose between

  • "exp": for exponential behavior

  • "log": for logarithmic behavior

  • "geo": for geometric behavior

  • "lin": for linear behavior

  • "quad": for quadratic behavior

  • "cub": for cubic behavior

  • float: here you can specifi any exponent (“quad” would be equivalent to 2)

  Default: "exp"

Returns:

Array containing the special range

Return type:

numpy.ndarray

Examples

>>> specialrange(1,10,4)
array([ 1.        ,  2.53034834,  5.23167968, 10.        ])
