linear_algebra.src.transformations_2d

2D Transformations are regularly used in Linear Algebra.

I have added the codes for reflection, projection, scaling and rotation 2D matrices.

scaling(5) = [[5.0, 0.0], [0.0, 5.0]]

rotation(45) = [[0.5253219888177297, -0.8509035245341184],

[0.8509035245341184, 0.5253219888177297]]

projection(45) = [[0.27596319193541496, 0.446998331800279],

[0.446998331800279, 0.7240368080645851]]

reflection(45) = [[0.05064397763545947, 0.893996663600558],

[0.893996663600558, 0.7018070490682369]]

Functions

projection(→ list[list[float]])
reflection(→ list[list[float]])
rotation(→ list[list[float]])
scaling(→ list[list[float]])
