How to store multiple image vectors into matrix rows?

    myFolder = 'C:\Users\Sana\Desktop\DermoscopyImages';
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
filePattern = fullfile(myFolder, '*.bmp');
bmpFiles = dir(filePattern);
immat=zeros(437580,200);
for k = 1:length(bmpFiles)
  baseFileName = bmpFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  imageArray = rgb2gray(imread(fullFileName));  %Read image and convert to Gray 
  imtovector=double(imageArray(:));             %convert 2D image into 1D vector
  immat(437580,k)=imtovector                    %Store image vectors into matrix
  imshow(imageArray);  % Display image.
  drawnow; % Force display to update immediately.
end

Any sort of help in this regard would be highly appreciated. Thanks in advance
