sfsnr2 computes the signal-to-noise (SNR) ratio in decibells.

The following example from tccs/intshape/fsyn uses the SNR computation to compare the convergence of two different methods.

SNR is computed according to the equation

$S N R = 10 \log_{10} (\frac{‖ s ‖_{2}^{2}}{‖ n ‖_{2}^{2}})$

The signal vector $s$ is in the standard input, the noise vector $n$ is in the file specified by noise= parameter.
