I'm creating a state space funktion in labview. Now i want to specify the entries of the matrices A,B,C and D. I have the entries in an excel table and i'm looking for a solution to import this entries into labview. I don't want to define them by hand because the matrices are of a wide structure.

First you need to convert the A,B,C,D matrices from 'string' to a State-Space model. You can use this example VIs as reference:
C:\Program Files (x86)\National Instruments\LabVIEW 2013\examples\Control and Simulation\Control Design\Model Construction\CDEx Creating SS Model from String Matrix.vi
Then if you create a Indicator out of the "CD Construct State-Space Model" like this:
Then you have the cluster that represents the state-space model, you can select the control, then use <CTRL-C> to copy into the 'clipboard'.
Then, open you State-Space function from simulation, select the 'state-space' parameter and use the 'Paste from clipboard' button. You should see your model parameters showing for you.

That works well, thank you!
