Interactively inputing a workspace table name

I want to use the input function to read in the name of a workspace file and then use that file, e.g.
datafilename = input('input the name of the training data table','s');
Mdl = fitrsvm(datafilename,'somevariablename');
where datafilename is the name of a table in the workspace (and somevariablename is a column header in that table). But I am unsuccessful in all my attempts to do this. Can anyone give me some help on this?

Yes. The easiest (waste less of your time, neater, simpler, faster, less buggy) solution is to avoid this situation entirely. The critical question is: how did those variables get into your workspace? Most likely you did not sit and type out the names of hundreds of variables: either they were imported e.g. using load, or perhaps created in a loop. In either case it is trivial to avoid the situation, e.g. load into an output argument:
S = load(...)
If you give us some more information on how the data get into your workspace then we can show you simple ways of accessing it.
