As simple as the formula is, finding the square footage is a little cumbersome. Webr = snr (xi,y) returns the signal-to-noise ratio (SNR) in decibels of a signal, xi, by computing the ratio of its summed squared magnitude to that of the noise y: r = mag2db(rssq(xi(:))/rssq(y(:))). y must have the same dimensions as xi. Use this form when the input signal is not necessarily sinusoidal and you have an estimate of the noise.
