cr.sparse.metrics.signal_noise_ratio¶
- cr.sparse.metrics.signal_noise_ratio(reference_arr, test_arr)[source]¶
Returns the signal to noise ratio between a reference array and a test array
- Parameters
reference_arr (jax.numpy.ndarray) – Reference signal (can be ND array)
test_arr (jax.numpy.ndarray) – Test signal (can be ND array)
- Returns
Signal to Noise Ratio between reference and test signals
Example
>>> x = jnp.ones(10) >>> y = 0.9 * x >>> signal_noise_ratio(x, y) DeviceArray(19.999998, dtype=float32)
