I have got a simulation file for a grid-tie inverter, which I am going to leave its image below. When I run the simulation, I receive the following error:

Error evaluating 'StopFcn' callback of block_diagram 'DC2ACGRID2'.
Caused by:
Vectors must be the same length.

I cannot figure out what vectors are causing this trouble. Any help is very much appreciated.

在 MATLAB Online 中打开

set_param('YourModelNameGoesHere', 'StopFcn', '')

then save your model.

As Swarooph said, problem is in the code, write it in M file and check it line by line.

Go to the "MODELING" tab on the simulink window.
In the Center click on "Model Settings".
Under Data Import/Export UNCHECK the box next to: "Single Simulation output:"
