title: matlab, how to export text and numerical data to a excel csv file?
body: <p>When I use the code below. I get the numerical data exported correctly however the first row is blank when there should be titles(headers) on the first row of each column. Any solutions?</p>
  
  <pre><code>clc 
  clear
  
  filename = 'file.csv'; 
  fileID = fopen(filename,'wt');
  %**************************************************************************
  %Sample data (note sample data are transposed row, i.e. columns) 
  
  sample1 = [1,2,3,4]';
  sample2 = [332.3, 275.8, 233.3, 275]';
  sample3 = [360, 416.7, 500, 360]';
  sample4= [-0.9, -0.9, -0.9, -0.9]';
  sample5 = [ 300000, 0, 0, 0]';
  
  A ={'text1','text2', 'text3', 'text4', 'text5'}; %'
  
  %***************************************************************************
  %write string to csv
  
  [rows, columns] = size(A);
  for index = 1:rows    
      fprintf(fileID, '%s,', A{index,1:end-1});
      fprintf(fileID, '%s\n', A{index,end});
  end 
  
  fclose(fileID);
  
  %***************************************************************************
  %write numerical data to csv
  
  d = [sample1, sample2, sample3, sample4, sample5];
  
  csvwrite(filename, d, 1);
