Adding "headers" (i.e. column/variable names) is easy if you convert the data to a table: https://www.mathworks.com/help/matlab/ref/array2table.html
However a heirarchy of column/variable names like you show is not possible in one table :https://www.mathworks.com/matlabcentral/answers/541568-nested-tables-with-duplicate-sub-column-names
You could create nested tables, but that does complicate accessing and processing your data.

Something like the following may be similar to what you want.
clear; clc;
combine_vector = randi(10,5,10);
Title1 = array2table(combine_vector(:,1:5),'VariableNames',compose('feature%d',1:5));
Title2 = array2table(combine_vector(:,6:10),'VariableNames',compose('Sfeature%d',1:5));
T = table(Title1,Title2)

There is no need to save them in different variables. Stephen's recommendation is absolutely right.
In case you would like to use data on column 1,6,11. You can directly retrieve them from the variable combine_vector as follows:
combine_vector = randi(10,28,75);
combine_vector(:,[1 6 11])
