newton.math.vec_allclose

newton.math.vec_allclose(a, b, rtol=1e-5, atol=1e-8)

Check whether two Warp vectors are element-wise equal within a tolerance.

Uses NumPy’s allclose tolerance criterion for finite elements: abs(a[i] - b[i]) <= atol + rtol * abs(b[i]). NaN values are never close. Infinite values are close only when they have the same sign.

Parameters:

• a (Any) – First vector.

• b (Any) – Second vector.

• rtol (float) – Relative tolerance.

• atol (float) – Absolute tolerance.

Returns:

True if all elements are close, False otherwise.

Return type:

bool
