Args |
initial_value
|
Initial value of the process.
|
damping
|
The rate at which the noise trajectory is damped towards the
mean. We must have 0 <= damping <= 1, where a value of 0 gives an
undamped random walk and a value of 1 gives uncorrelated Gaussian noise.
Hence in most applications a small non-zero value is appropriate.
|
stddev
|
Standard deviation of the Gaussian component.
|
seed
|
Seed for random number generation.
|
scope
|
Scope of the variables.
