Basic vector and matrix operations using pylinalg.

from pylinalg import vec, mat import numpy as np v = vec([1, 2, 3]) print(v.length()) m = mat([[1, 0], [0, 1]]) w = m @ vec([4, 5]) print(w)

Debug

Known issues

breakingVersion 0.6.0 changed the vector and matrix classes from mutable to immutable (like tuples). Assigning to indices now raises TypeError.

fix

Use functions like vec.set(index, value) or create new vectors instead of index assignment.

affects: >=0.6.0

gotchaThe multiplication operator @ is overloaded for matrix multiplication but not element-wise. Use numpy functions for element-wise operations.

fix

For element-wise multiplication, use numpy.multiply(a, b) or the * operator on underlying numpy arrays.

affects: all

deprecatedThe 'angle' parameter in rotation functions (e.g., quat.from_angle_axis) has been renamed to 'theta' in v0.6.0.

fix

Use theta=... instead of angle=... in rotation constructors.

affects: >=0.6.0
