MATLAB: Multiple tables from one table

MATLABtables

I need to create table of tables, or any other way to export data from the given data table.

It is not recommended practive to put your tables as array type, highly error prone and variable name changes. Your should assign as

subtable(:, i) = data(x, :)    % for each iteration height of the table must match

It is recommended to use cell array as

subtable{i}= data(x, :) ;

varfun(@(c) {vertcat(c{:})}, table1, 'GroupingVariables', 'Var1', 'InputVariables', 5:width(table1))

varfun(@(c) {vertcat(c{:})}, table1, 'GroupingVariables', {'Var1', 'Var2'}, 'InputVariables', 5:width(table1))

varfun(@(c) {vertcat(c{:})}, table1, 'GroupingVariables', {'Var1', 'Var2', 'Var3'}, 'InputVariables', 5:width(table1))

Just figured this out: have to use array2table,

   T = array2table(rand(30,8), ...
      'VariableNames', {'var1' 'var2' 'var3' 'var4' 'var5' ...
      'var6' 'var7' 'var8'});

However if you want to assign other properties besides names, you have to do that separately, unlike the table command,

T.Properties.VariableUnits = {'kg' 'm' 'W' 's' 'g' 'kg' 'm' 'W'};
