MATLAB: Add data in a table according to the variable names.

tables

I have written a code with a for loop and at the end of each iteration the output is a table with the corresponding variable names, something like this:
head = {'level_RI1','inflow_RI1','outflow_RI1'}
B.Properties.VariableNames = head;
the second iteration output is a table like this:
head = {'level_R2','inflow_R2','outflow_R2'}
B.Properties.VariableNames = head;
at the end I want to merge the results of each iteration in a final table which variable names are:
Result.Properties.VariableNames = {'level_RI1','inflow_RI1','outflow_RI1','level_R2','inflow_R2','outflow_R2'}
But so far I just get the table to overwrite itself at the end of the iterations and the result just contain the final iteration:
Result.Properties.VariableNames = {'level_R2','inflow_R2','outflow_R2'}
I'd appreciate any help 🙂

  • I can't tell if the question is about just the variable names, or the tables themselves. So this may be answering a different question than you asked.
    If you have several tables with variable names that don't conflict, just horzcat them:
    result = [T1, T2, T3]
    Presumably you have many tables, so you can't really hard-code that line. If you store each individual table in a cell array at each iteration of your loop, you can expand that cell array to horzcat them:
    for i = ...
    myTables{i} = ...
    end
    result = [myTables{:}];
