jax.lax.shift_left

jax.lax.shift_left(x, y)

Elementwise left shift: \(x \ll y\).

This function lowers directly to the stablehlo.shift_left operation.

Parameters:

• x (ArrayLike) – Input arrays. Must have matching integer dtypes. If neither is a scalar, x and y must have the same number of dimensions and be broadcast compatible.

• y (ArrayLike) – Input arrays. Must have matching integer dtypes. If neither is a scalar, x and y must have the same number of dimensions and be broadcast compatible.

Returns:

An array of the same dtype as x and y containing the element-wise left shift of each pair of broadcasted entries.

Return type:

Array
