+  """One-dimensional linear interpolation.
+
+  JAX implementation of :func:`numpy.interp`.
+
+  Args:
+    x: N-dimensional array of x coordinates at which to evaluate the interpolation.
+    xp: one-dimensional sorted array of points to be interpolated.
+    fp: array of shape ``xp.shape`` containing the function values associated with ``xp``.
+    left: specify how to handle points ``x < xp[0]``. Default is to return ``fp[0]``.
+      If ``left`` is a scalar value, it will return this value. if ``left`` is the string
+      ``"extrapolate"``, then the value will be determined by linear extrapolation.
+      ``left`` is ignored if ``period`` is specified.
+    right: specify how to handle points ``x > xp[-1]``. Default is to return ``fp[-1]``.
+      If ``right`` is a scalar value, it will return this value. if ``right`` is the string
+      ``"extrapolate"``, then the value will be determined by linear extrapolation.
+      ``right`` is ignored if ``period`` is specified.
+    period: optionally specify the period for the *x* coordinates, for e.g. interpolation
+      in angular space.
+
+  Returns:
+    an array of shape ``x.shape`` containing the interpolated function at values ``x``.
+
+  Examples:
+    >>> xp = jnp.arange(10)
+    >>> fp = 2 * xp
+    >>> x = jnp.array([0.5, 2.0, 3.5])
+    >>> interp(x, xp, fp)
+    Array([1., 4., 7.], dtype=float32)
+
+    Unless otherwise specified, extrapolation will be constant:
+
+    >>> x = jnp.array([-10., 10.])
+    >>> interp(x, xp, fp)
+    Array([ 0., 18.], dtype=float32)
+
+    Use ``"extrapolate"`` mode for linear extrapolation:
+
+    >>> interp(x, xp, fp, left='extrapolate', right='extrapolate')
+    Array([-20.,  20.], dtype=float32)
+
+    For periodic interpolation, specify the ``period``:
+
+    >>> xp = jnp.array([0, jnp.pi / 2, jnp.pi, 3 * jnp.pi / 2])
+    >>> fp = jnp.sin(xp)
+    >>> x = 2 * jnp.pi  # note: not in input array
+    >>> jnp.interp(x, xp, fp, period=2 * jnp.pi)
+    Array(0., dtype=float32)
