Saving a new table for every loop iteration
显示 更早的评论
I am having trouble saving a function output in a for loop with a different variable name
variable_max = size(variable_scan,1);
for i = 1:variable_max
data_name = variable_scan{i,1};
column_name = variable_scan{i,2};
name = strcat('data_table',num2str(i));
name = dataextract(data,data_name,column_name);
end
dataextract outputs a table. I would like to save this output with something like table_'column_name'

Yes, that is indeed a difficult thing to do. And also completely pointless because MATLAB has much neater, simpler, easier and more efficient methods of handling data.
Magically trying to create or access variable names is slow, complex, buggy, obfuscated, hard to debug, and insecure. In contrast using indexing is neat, simple, fast, easy to debug, and very efficient.

Don't do that. Dynamic variable creation is a bad idea and totally unnecessary.
Use a cell array.
data = cell(variable_max,1);
column_name = cell(variable_max,1);
%and preallocate other variables, this is important if you want your code to be faster
for k=1:variable_max
...
...
column_name {k,1} = ...
data{k,1} = dataextract(...)
end
Now you have all your tables under one variable. You can access them by indexing.
