MATLAB: How to save separate ‘.mat’ files with the image name including it

image processingmachine learning

I am creating the data base for the Microscopic cell 400 images that extracts the alive and dead cells by calling gerect func. I need to save the result in the .mat files starting with image name.I am using 'try' and 'catch' to generate the database. my code as follows:
[fname path]=uigetfile('.jpg','open a cell pic');
fname=strcat(path,fname);
a=imread(fname);
im=rgb2gray(a);
imshow(im);
title('input image');
while(1)
  rect=datapoints(im); % calling getrect function to extract  points
    %c=input('enter the label: \n');
      try 
        load data
        trainSets=[rect c];
        data=[data; trainSets];
      save data.mat data;
               catch
        data=[rect c];
              save data.mat data
    end
this program creating only one .mat File name named as 'data.mat' , but i need .mat for each image i open.as image1.mat, then image2.mat and so on Plz help !!!!!!

 I am using 'try' and 'catch' to generate the database.
Although this works, it is cleaner to check for the existence of the file:
if exist('data.mat', 'file')
  FileData  = load('data.mat');
  trainSets = [FileData.rect, FileData.c];
  data      = [data; trainSets];
else
  data = [rect c];
  save('data.mat', 'data');
end
If you want to modify the file name, see: FAQ: Process a sequence of files.
Folder = cd;
for k = 1:10
  File     = fullfile(Folder, sprintf('image%d.mat', k))
  FileData = load(File);
  ...
end
The same works for
save(File, 'data')
