Indexing inside variables name

Hello everybody,

I have a set of arrays inside the workspace whose names are like the followings: Data1_Asc, Data1_BML, Data2_Asc, Data2_BML... Datan_Asc,Datam_BML.

I want to divide these variables into n different .mat files where each variable inside everyone of these files would be named as:

Data1_Asc, Data1_BML.

Any suggestion?

Thanks

"Indexing inside variables name"

Forcing pseudo-indices into variable names is much less efficient than using actual indices.

Accessing numbered variable names forces you into writing slow, complex, inefficient, fragile, obfuscated code.

You did not tell us the most important information: how did you get all of those variables into the workspace?

for k = 1:N
    v1 = sprintf('Data%u_Asc',k);
    v2 = sprintf('Data%u_BML',k);
    fn = sprintf('File%u.mat',k);
    save(fn,v1,v2)
end

Better data design would use exactly the same variable names in every file.
