'signals' in load() requires Datafeed Toolbox?

3 views (last 30 days)
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.

Please give the following information about your workflow so that the community can assist you more effectively:
  1. What kind of data is associated with the field 'signals'?
  2. Do you receive a similar error if you change the field name ‘signals’ to something else?

It is not possible to selectively load() fields from a struct saved in a mat
