Utilities¶
Provides common utility functions.
- pyrr.utils.all_parameters_as_numpy_arrays(fn)[source]¶
Converts all of a function’s arguments to numpy arrays.
Used as a decorator to reduce duplicate code.
- pyrr.utils.parameters_as_numpy_arrays(*args_to_convert)[source]¶
Converts specific arguments to numpy arrays.
Used as a decorator to reduce duplicate code.
Arguments are specified by their argument name. For example
@parameters_as_numpy_arrays('a', 'b', 'optional') def myfunc(a, b, *args, **kwargs): pass myfunc(1, [2,2], optional=[3,3,3])
- pyrr.utils.solve_quadratic_equation(a, b, c)[source]¶
Quadratic equation solver. Solve function of form f(x) = ax^2 + bx + c
- Parameters:
a (float) – Quadratic part of equation.
b (float) – Linear part of equation.
c (float) – Static part of equation.
- Return type:
list
- Returns:
List contains either two elements for two solutions, one element for one solution, or is empty if no solution for the quadratic equation exists.
