Generates temporally autocorrelated random numbers with a mean, standard deviation, and autocorrelation you specify.
colored_noise(timesteps, mean, sd, phi)
| timesteps | The number of temporally autocorrelated random numbers (one per timestep) you want. |
|---|---|
| mean | The mean of the temporally autocorrelated random numbers. |
| sd | The standard deviation of the temporally autocorrelated random numbers. |
| phi | The temporal autocorrelation. 0 is white noise (uncorrelated), positive values are red noise (directly correlated) and negative values are blue noise (inversely correlated). |
A vector of temporally autocorrelated random numbers.
