How can save cell array (numbers and string ) using xlswrite ?

hi, i have this code, i tried to store the cell arry (Bandwidth1) in excel file inside iteraion , but the excel file results empty vaule !

lfiles = dir('*.xlsx'); % You are in the folder of xl files
      Nfiles = length(xlfiles) ;  % number of xl files
      % loop for each file 
      for i = 1:Nfiles
      fname = xlfiles(i).name ;   % file name
      [~,~,dat] = xlsread(fname) ;   % read the file 
       p2= strcmp(dat(:,1),'sim_seconds') ;    
        simsecond (i)= cell2mat(dat(p2,2));
        dcachmi= strcmp(dat(:,1),'system.cpu00.dcache.overall_misses::total') ;      
         dcachemi00 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu01.dcache.overall_misses::total') ;      
         dcachemi01 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu02.dcache.overall_misses::total') ;      
         dcachemi02 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu03.dcache.overall_misses::total') ;      
         dcachemi03 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu04.dcache.overall_misses::total') ;      
         dcachemi04 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu05.dcache.overall_misses::total') ;      
         dcachemi05 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu06.dcache.overall_misses::total') ;      
         dcachemi06 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu07.dcache.overall_misses::total') ;      
         dcachemi07 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu08.dcache.overall_misses::total') ;      
         dcachemi08 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu09.dcache.overall_misses::total') ;      
         dcachemi09 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu10.dcache.overall_misses::total') ;      
         dcachemi10 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu11.dcache.overall_misses::total') ;      
         dcachemi11 = cell2mat(dat(dcachmi,2)); 
         dcachmi= strcmp(dat(:,1),'system.cpu12.dcache.overall_misses::total') ;      
         dcachemi12 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu13.dcache.overall_misses::total') ;      
         dcachemi13 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu14.dcache.overall_misses::total') ;      
         dcachemi14 = cell2mat(dat(dcachmi,2)) ;
         dcachmi= strcmp(dat(:,1),'system.cpu15.dcache.overall_misses::total') ;      
         dcachemi15 = cell2mat(dat(dcachmi,2)) ;
         dcachemitotal(i)=dcachemi15+dcachemi14+dcachemi13+dcachemi12+dcachemi11+dcachemi10+dcachemi09+dcachemi08+dcachemi07+dcachemi06+dcachemi05+dcachemi04+dcachemi03+dcachemi02+dcachemi01+dcachemi00;
         
         Bw1(i)= (dcachemitotal(i)*64);
         Bw(i)= Bw1(i) ./simsecond (i);   
         Bandwidth1= sizeconvert ([Bw(i)]) ;
         
                      
        %%%%%%%%%%%%%   this is my question %%%%%%%%%%%%%%%%
        ca{i, 1} = Bandwidth1;   %  how can save this array in the Excel file ? 
          
      end
            
      col_header={'Bandwidthsize'};     
      xlswrite('B.xlsx',col_header,'Sheet1','A1');     
      cellReference = sprintf('A2');
     xlswrite('B.xlsx', ca, 'Sheet1', cellReference);

Try using writetable

[Stephen23]

Using numbered variables is a sign that you are doing something wrong.

Copy-and-pasting code is a sign that you are doing something wrong.

Rather than this copy-and-paste fifteen times:

dcachmi= strcmp(dat(:,1),'system.cpu00.dcache.overall_misses::total') ;      
         dcachemi00 = cell2mat(dat(dcachmi,2)) ;
dcachmi= strcmp(dat(:,1),'system.cpu01.dcache.overall_misses::total') ;      
         dcachemi01 = cell2mat(dat(dcachmi,2)) ;
...

you should use a loop with:

• sprintf to generate those character vectors, and
• indexing to store the result in one vector or matrix,

then this incredible line of code:

dcachemitotal(i)=dcachemi15+dcachemi14+dcachemi13+dcachemi12+dcachemi11+dcachemi10+dcachemi09+dcachemi08+dcachemi07+dcachemi06+dcachemi05+dcachemi04+dcachemi03+dcachemi02+dcachemi01+dcachemi00;

becomes one simple sum operation.

thanks for your notice , i update the code based own your comments, but still not able to write all the values for the cell array ( Bandwidth1) just last value in the table !, i tried with writable but its still same problem,

how can store all values for the variable (Bandwidth1) for the loop in excel file?

xlfiles = dir('*.xlsx'); 
      Nfiles = length(xlfiles) ;  
      for i = 1:Nfiles
      fname = xlfiles(i).name ;   
      [~,~,dat] = xlsread(fname) ;   
       p2= strcmp(dat(:,1),'sim_seconds') ;    
        simsecond (i)= cell2mat(dat(p2,2));
        dcachmi= strcmp(dat(:,1),'system.cpu00.dcache.overall_misses::total') ;      
        dcachemi00 = cell2mat(dat(dcachmi,2)) ;
        dcachemitotal(i)=dcachemi00;
        Bw(i)= (dcachemitotal(i)*64)./simsecond (i);
        Bandwidth1= sizeconvert ([Bw(i)]) ;
       
        cellReference = sprintf('A1');
        xlswrite( 'B.xlsx',Bandwidth1,'Sheet1',cellReference);
         
      end
