I am trying to load data from a structure, which has two fields - signals and meta_data.

load([PathName, file_name],'meta_data','signals');

This throws an error:

'signals' requires Datafeed Toolbox.

Is the 'signals' field name conflicting with MATLAB's reserved keywords? I was trying to check load documentation but didn't find anything.

What kind of data is associated with the field 'signals'?
Do you receive a similar error if you change the field name ‘signals’ to something else?
