North Atlantic meridional overturning circulation variations from GRACE ocean bottom pressure anomalies. The conjugate gradient method can be applied to an arbitrary n-by-m matrix by applying it to normal equations A T A and right-hand side vector A T b, since A T A is a symmetric positive-semidefinite matrix for any A.The result is conjugate gradient on the normal equations (CGNR).

The Hurst exponent, H, is defined in terms of the asymptotic behaviour of the rescaled range as a function of the time span of a time series as follows; [() ()] =,where; is the range of the first cumulative deviations from the mean() is the series (sum) of the first n standard deviations[] is the expected valueis the time span of the observation (number of data points in a time series) A broken power law is a piecewise function, consisting of two or more power laws, combined with a threshold.For example, with two power laws: for <,() >.Power law with exponential cutoff. Multivariate normal distribution Example #3. Pretending the above generated signal as a continuous signal, we would like to convert the signal to discrete-time equivalent by sampling.
