Hello,
I created a three phase grid as an Simulink model.
After adding 3-phase voltage source blocks and starting the simulation I get this error: "Index exceeds matrix dimensions"
I am using Matlab version 2017a and tried to get more detailed information about the error using: set_param(gcs,'SimulationCommand','update');
But I didnt get any new informations about the error
Can someone help me solving this problem?

Hi Michael,
The error simply means that you are trying to execute an operation that wants to access a cell of an array (could be matrix, vector ...) which dimensions do not correspond to what you are trying to access. For instance, you get that error if you have a 3x3 matrix and ask for the element (4,3). It's a quite common error if you are using loops.

Hey, thanks for your reply. I am not using any MATLAB Function Blocks and it seems that I am not refering to any signal that does not exist.

Solved my problem:
1. Located the blocks which generated the error.
2. Recreated every block. This solved the problem.
Anyway, thanks for your effords

Hi,
I have also experienced this error when a model contains a s-function builder block that has not been built. Build the s-function and the error disappears, utterly strange error message...
