Usage: @1dDiffMag file.1D * Computes a magnitude estimate of the first differences of a 1D file. * Differences are computed down each column. * The result -- a single number -- is on stdout. * But (I hear you say), what IS the result? * For each column, the standard deviation of the first differences is computed. * The final result is the square-root of the sum of the squares of these stdev values.
