Lookup Table Class

[DFriend01]

Purpose

The purpose of the lookup table is to take a table of $(x,y)$ mappings and perform interpolation to evaluate for values of $x$ that do not exactly fall upon a defined mapping.

Description

The task is to create a lookup table class LUT. Create a file named lut.py in the controller/common directory and write the class there.

Inputs:

• 2D array of $(x,y)$ mappings for interpolation
• The interpolation method
  • linear for linear interpolation
  • spline for spline interpolation

Class Functionality:

• The LUT class should implement a method to perform interpolation.
• Add any other functionality you think might be useful

Testing:

• Write your unit tests in tests/unit/common/test_lut.py. See the boat simulator tests for examples on how to implement tests with pytest.
