Solve differential equation with measurement results

[nanomaniac]

Hello everybody,

I would like to solve a (simple) differential equation:

y ' (x)  +  p * y (x)  =  q(x)

The special issue with my problem is that  q(x)  is given as measurement data (e.g. array of numerical data). A numerical solution of y(x) would be sufficient for me. Unfortunately, I couldn't find any solution yet. Any help would be appreciated.

Thanks a lot in advance

Best regards

The best way probably is to use the Control Design and Simulation Module. There is an webcast to be found here youtube under: Solving a differential equation on LabVIEW  and a lot of documentation over the web.

Onother way would be to use the Euler or Runge Kutta calcation, included in LabVIEW Full.
