When I read an excel file by "readtable" I get the following file as an example
I am interested in getting the frequency range of 102-105 MHz only
How can I cut the file?
** The original file contains a lot of columns so I am interested in entering the frequency range

Use detectimportoptions and set the opts.SelectedVariableNames to be the variables (columns) you want to import. You can see several examples here. Here is another example from the readtable documenation page.
If your file contains a header row, those names can become the variable names. However, your specific request - having MATLAB figure out which columns to import by just entering a frequency range - is not native functionality. This is not to say you couldn't implement something, but it's on you to create the code to do that.
