    w -= 0.01 * dw  # Update weights
    b -= 0.01 * db  # Update bias
    return (w, b), (w, b)

# Initial weights and gradients
weights = (jnp.array(0.5), jnp.array(0.1))
gradients = [(jnp.array(0.2), jnp.array(0.05)) for _ in range(10)]

final_weights, updates = lax.scan(gradient_step, weights, gradients)
print("Final Weights:", final_weights)

Simulation Example: Particle Dynamics

def particle_step(carry, t):
    position, velocity = carry
    new_position = position + velocity * t
    return (new_position, velocity), new_position

# Initial state
state = (jnp.array(0.0), jnp.array(1.0))  # Position and velocity
time_steps = jnp.arange(0, 10, 1)

final_state, trajectory = lax.scan(particle_step, state, time_steps)
