I have developed a simulink file in matlab 2022a but when i connect a dc source it is showing error as incorrect matrix dimension. I am not using any matlab functions i th simulation only switches and dc source.

Hello,
This type of error typically arises from a mismatch in signal or port dimensions rather than a problem with the DC source itself. Carefully checking the block inputs and using signal dimension displays can help quickly identify and resolve the issue.
  • Ensure that all blocks connected to each other are working with signals of the same size.
  • Check that all data inputs to the Switch block have the same dimensions.
I hope this helps resolves your query!
