Hi @Jagadeesh N,

You are likely encountering this issue as MATLAB is not able to recognize a file at the filepath specified. The following could be the reasons:

1. Files indeed do not exist at the filepath you have specified, in which of the case you need to ensure again that everything is in place.
2. The file's naming is incosistent with the standards MATLAB uses.

You may use the following documents relevent to resolve your issue:
