Hello @Manikandan Raju,

It appears that you are experiencing an issue with the "emd" function and encountering an error.

Upon debugging the code, it has been identified that the IMF (Intrinsic Mode Function) is an empty matrix with a size of 1024x0, causing an error during vector slicing.

To resolve this issue, I recommend referring to the documentation of the "emd" function for further guidance:

I hope these suggestions help you resolve the issue you are facing
