JAX’s arange function is the first building block. Here’s a quick example:

import jax.numpy as jnp

# Generate an array of values
arr = jnp.arange(0, 10, 1)
print(arr)

Step 3: Define the Loop Function

To utilize the loop carry functionality, you need a function that carries states across iterations. Use JAX’s lax.scan for this purpose:

from jax import lax

# Define a function to carry over states
def loop_body(carry, x):
    carry = carry + x  # Example operation
    return carry, carry

# Initial carry state
init_carry = 0

# Apply lax.scan
final_carry, outputs = lax.scan(loop_body, init_carry, arr)
print("Final Carry:", final_carry)
print("Outputs:", outputs)

Step 4: Optimize with JIT Compilation

import jax

def gradient_step(carry, x):
    w, b = carry  # Unpack weights and bias
    dw, db = x    # Unpack gradients
    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)
print("Final State:", final_state)
print("Trajectory:", trajectory)
