geoclide.mathope module

geoclide.mathope.clamp(val, val_min, val_max)

Clamps val into the range [val_min, val_max]

Parameters:

valfloat

The scalar to be clamped

val_minfloat

The minumum value

val_maxfloat

The maximum value

Returns:

outfloat

The result of the clamp

Examples

>>> import geoclide as gc
>>> gc.clamp(4, val_min=5, val_max=11)
5

geoclide.mathope.quadratic(a, b, c)

Resolve the quadratic polynomial: ax**2 + bx + c

• where x is the quadratic polynomial variable and a, b and c the coefficients

Parameters:

afloat | 1-D ndarray

The first coefficient(s) of the quadratic polynomial

bfloat | 1-D ndarray

The second coefficient(s) of the quadratic polynomial

cfloat | 1-D ndarray

The third coefficient(s) of the quadratic polynomial

Returns:

bbool | 1-D ndarray

If the quadratic can be solved return True, else False

x0float | None | 1-D ndarray

The first solution(s)

x1float | None | 1-D ndarray

The second solution(s)

Notes

If There are 2 solutions x0 < x1. And if there is only one solution x0 = x1.

Examples

>>> import geoclide as gc
>>> a = 2
>>> b = -5
>>> c = 0
>>> gc.quadratic(a, b, c)
(True, 0.0, 2.5)
