First step with matlab

Thanks a lot for this example.

I still have a problem to run this script, the command window return me :

Undefined variable “org” or class “org.orekit.data.DataProvidersManager.getInstance”.
Error in PropagationDistribution (line 19)
DM=org.orekit.data.DataProvidersManager.getInstance()

Have got any idea to solve this issue ?

Thanks
