bessel_j#
- deepinv.physics.functional.bessel_j(n, x)[source]#
Computes the Bessel function of the first kind \(J_v(n, x)\) for order \(n\) and input \(x\).
Uses native Torch if available, otherwise falls back to SciPy.
- Parameters:
n (int) – Order of the Bessel function.
x (torch.Tensor) – Input tensor.
- Returns:
Tensor representing \(J_v(n, x)\).
- Return type:
