How to compare two string columns from different tables?

I have been trying to write a title for a plot using a table that I have for the variables (see the pictures), and I am aiming for the title to look like this: "Variable name" + " unit " + 10^"decimal point".

The struggle now is that I could not find out how to compare both the variable name colums between the two tables and I am also not sure how to write them in the title through a loop everytime. I ve had some trials but no success

for k = 1:numel(U)
    X = T.Variable==U(k);
    Var2=Variableunits.Variable;%the table that contains the units and the decimal factor that should be used.
    Num2= size(Var2,1);
    for j=  1:Num2
        if strcmpi(Var2{i},U(k)) == 0 % in case the  the a variable from the arrray U and from the column Var2 are identical, Im not sure if it is right.
        title(Var2{i},Variableunits.unit,Variableunits.Faktor); % write the variable, its unit and factor (I know it is not written right.)
        end
    end
end 

Thanks a lot in advance in case someone can help!

Please attach a sample subset of VariableUnits not just an image of it. Based on the image, I suspect that you are not accessing the columns properly.

Hi Walter, Thanks for the reply.

I just edited and attached a matlab table that contains the units and factor of the variables.

    for j=  1:Num2
        if strcmpi(Var2{i},U(k)) == 0 % in case the  the a variable from the arrray U and from the column Var2 are identical, Im not sure if it is right.
 

Your for loop is in variable j, but you are indexing Var2 at i where i is not initialized in the code you posted. That would leave i as sqrt(-1) which would be an error as an index.

title(Var2{i},Variableunits.unit,Variableunits.Faktor); % write the variable, its unit and factor (I know it is not written right.)

Try

        title(Var2{i},Variableunits.unit + " " + Variableunits.Faktor); % write the variable, its unit and factor (I know it is not written right.)

Us = {'E1_ABD_FoamEventCnt','E1_LD_ActualStatus','H1_PRESSURE_S15hPa','H2_PRESSURE_S03mmHg','H2_PRESSURE_S07mmHg','H2_TMP_PDmdaPa'};
U = categorical(Us);

for k = 1:numel(U)
    Var2 = Variableunits.Variable;%the table that contains the units and the decimal factor that should be used.
    Num2 = size(Var2,1);
    for i = 1:Num2
        if Var2(i) == U(k)
          thisunit = Variableunits.Unit(i);
          if ismissing(thisunit)
              thisunitname = '';
          else
              thisunitname = string(thisunit);
          end
          title(string(Var2(i)) + " " + thisunitname + " " + string(Variableunits.Factor(i)), 'Interpreter', 'none');
        end
    end
end

Thanks a lot! It is working :)
