Hey there,

This error is outputted when the file you want to read does not exist. Make sure that the file you are reading is correctly named and that is exists in the working directory. I am attaching the documentation as well in case you have any further questions. https://in.mathworks.com/help/matlab/ref/xlsread.html

The basic syntax is as follows:

xlsread("test.xlsx")

This should not give any errors if the file is named "test.xlsx".
