add cell or struct as title matlab plot

Hi,

See my script below, I need to add the changing variable 'num' as title name. How can i fix that?

for i = 3:3
    num = subFolders(i).name
    num2 = struct2cell(num)
    folder = ['C:\Users\dit\Documents\MATLAB\RawData\',num];  f = dir(fullfile(folder,'*.csv')); g = numel(f);
figure
title('How can I add num here?')
 for k = 1:g
     filename = fullfile(f(k).folder, f(k).name);
     CSVData = readmatrix(filename, 'Range', 1, 'Delimiter', ',');  [filepath,name,ext] = fileparts(filename); indexCSV = [(0:size(CSVData,1)-1)' CSVData];
     xC{k,1}=CSVData(:,7); yC{k,1}=CSVData(:,8); zC{k,1}=CSVData(:,9); radC{k,1}=CSVData(:,2)/2;
     indexC =indexCSV(:,1);     [valCL, idxCL] = max(indexC);
     plot3(xC{k,1},yC{k,1},zC{k,1},'-b')   
     hold on
 end
   folder = ['C:\Users\dit\Documents\MATLAB\Centerlines_Python\',num];  f = dir(fullfile(folder,'*.txt')); g = numel(f)-1;
 for i = 0:g
    Ofilename = fullfile(f(i+1).folder, f(i+1).name);    
    DataText=load(Ofilename);  
    x = DataText(:,1);    y = DataText(:,2);    z = DataText(:,3);
    plot3(x,y,z,'-')
    hold on
 end

 pause
 close
end

Since ‘num’ should be a simple character vector (at least it is when I tested this in R2020b), one of these should work:

title(num)                                      % Includes Extension
title(extractBefore(num,'.'))                   % Removes Extension
