I'have a file named 'HIS_all.csv' and i used datastore function to store it as follows

    ds = datastore('HIS_all.csv', 'DatastoreType', 'tabulartext', 'TreatAsMissing', 'NA');

datastore by default makes cell array named VariableNames containing the variable names. Is there any way to do this with rows. i.e. i need to make a unique id for each row that will be passed with it to the map function to make something like this

addmulti(intermidiateValuesOut,key,{ind});

I'd like the key here to be the real id in the file. for example if I'm working with row number 10000, I'd like the key to be 10000. Is this possible?

Please Help Thanks in advance
