Table Variable Name-dot indexing

I need to creat a table with the following variable names :

A1 B1 C1 A2 B2 C2 A3 B3 C3 , ... An Bn Cn X Y Z

A1 B1 C1 are Table's variable names that their values come from seprate arrays A, B, and C. Also, the last three column of the table, X, Y, AND Z, have nothing to do with aformentioned arrays. Any thoughts how to define variable names as above?

Here are what I wrote. Besides getting an error "Unable to perform assignment because dot indexing is not supported for variables of this type" , I believe there is definately a way more efficient way to do that.

    % Assume A, B, and C  as Location %d–Building Loss, Location %d–Time Element Loss, and Location %d–Total Loss 
    for n=1:Nbu
        VarName{1 , (n-1)*3+1} = sprintf('Location %d–Building Loss', n);
        VarName{1 , (n-1)*3+2} = sprintf('Location %d–Time Element Loss', n);
        VarName{1 , (n-1)*3+3} = sprintf('Location %d–Total Loss', n);
    end
    
    % Assume Building Loss, Time Element Loss, and Total Loss(Building + Time Element Loss) as X,Y, and Z; VARIABLESS' NAMES OF THE LAST THREE COLUMNS 
    VarName{1 , Nbu*3+1} = sprintf('Building Loss', n);
    VarName{1 , Nbu*3+2} = sprintf('Time Element Loss', n);
    VarName{1 , Nbu*3+3} = sprintf('Total Loss(Building + Time Element Loss)', n);

    Table1.Properties.VariableNames = VarName(1,:);

Which MATLAB release are you using?

Could you confirm that class(Table1) is table ?

I'm using R2020a release.

Good point Walter, Table 1 is cell.

Here is the code i wrote to create Table 1. Is there any way to create table instead?

for i = 1:Nev
        for j=1:Nbu
            Table1{i,(j-1)*3+1} = BuildingLoss{:,i}(:,j) ; 
            Table1{i,(j-1)*3+2} = BuildingTimeElementLoss{:,i}(:,j); 
            Table1{i,(j-1)*3+3} = BuildTotLoss{:,i}(:,j) ;
        end
        %Last three columns
        Table1{i,(j-1)*3+4} = CoverageA(i,1);
        Table1{i,(j-1)*3+5} = CoverageD(i,1);
        Table1{i,(j-1)*3+6} = TotalLoss(i,1);

end

cell2table(Table1, 'VariableNames', VarName(1,:))

Thanks, table creation problem solved! Now back to my initial question, is there a more efficient way to define the variables' names than I did?

[Walter Roberson]

compose() and use "" delimited format

[compose("Location %d-Building loss", 1:Nbu),
 compose(...) 
 compose(...)]

and reshape to a row vector.

[Mos_bad]

Thanks, That worked and "compose" reduced several line of codes.

Last question, Any thoughts on rewriting the nested for loop in my previous comment?

        for j=1:Nbu
            Table1{i,(j-1)*3+1} = BuildingLoss{i}(:,j) ; 
            Table1{i,(j-1)*3+2} = BuildingTimeElementLoss{i}(:,j); 
            Table1{i,(j-1)*3+3} = BuildTotLoss{i}(:,j) ;
        end

could be:

       Table1(i,:,1) = num2cell(BuildingLoss{i}, 1);
       Table1(i,:,2) = num2cell(BuildingTimeElementLoss{i}, 1);
       Table1(i,:,3) = num2cell(BuildingTotLoss{i}, 1);
       
       Table1(i,:,4) = {CoverageA(i,1)};  %same value for each j
       Table1(i,:,5) = {CoverageD(i,1)};  %same value for each j
       Table1(i,:,6) = {TotalLoss(i,1)};  %same value for each j

and reshape afterwards to collapse the second and third dimension together. Or better yet, don't.
