Using values from an array as titles in generated figures

Hi,

So I have some code that runs through some data given to it multiple times, and creates figures based upon different apsects of the code.

What I want it to do now is to use an array (or another method) to name the figures base upon what run of the program it is on.

My current code is:

cd('....')
output_file='....'

var_name = ['VAR1, VAR2, VAR3, VAR4'];

for count_1 = 1:4;
    current_var = var_name(count_1);

      for count_2 = 1:10; 

          data = load(....)

          current_data = count_1 + 4;

          data_1 = data(:,1); 
          data_2 = data(:,2); 
          data_3 = data(:,current_data);       

          data_figure= figure('Visible','off');      
          axes1 = axes('Parent', data_figure, 'ZGrid', 'on', 'YGrid', 'on');     
          view(axes1,[0.5 90]);       
          xlim(axes1,[-0.01 0.25]);      
          hold(axes1, 'all');  
          surf(data_reshape_1,data_reshape_2,data_reshape_3, 'Edgecolor', 'none');        
          colorbar;       

          %ISSUE IN THE NEXT FEW LINES
          title([num2str(count_2),'ns:  ',[num2str(current_var),'.....']]);      
          xlabel('.....');     
          ylabel('.....');      
          ylabel(colorbar, [num2str(current_var)]);     
          set(gca, 'XGrid', 'off');     

      end

end

Everything works fine, apart from the fact that instead of using the values of what is in var_name in turn, it takes the letters from the first value in the array, i.e V, A, R, 1 and not the desired, VAR1, VAR2, VAR3, VAR4

Any help would be great.

I suspect you just need something like

eval( current_var )

but I never use eval so I'm not 100% sure that is the correct syntax. Someone else will no doubt answer more confidently on that soon enough!

var_name = ['VAR1, VAR2, VAR3, VAR4'];

I think you rather want it as a cell:

var_name = {'VAR1', 'VAR2', 'VAR3', 'VAR4'};

and then title with

title([num2str(count_2) 'ns: '  ', var_name{count_1} '.....'])
