Hello there
I need to reproduce the results of a simulation found elsewhere. The model is a set of nonlinear differential equations with 5 variables (x1,x2,z,y1,y2). To the equations on the derivatives of x1 and y1 I need to add a Gaussian noise with standard deviation set to 0.025. To the ones on x2 and y2, 0.25.
Something like: dx1/dt=fx1(x1,x2,y1,y2,z)+WGN(0,0.025), dx2/dt=fx2(x1,x2,y1,y2,z)+WGN(0,0.25)
and so on
Could someone help me out with directions, methods to be used and etc, please?
Thank you.
Ed
