you can get the listing for all the images in a folder by using imageFiles = dir('*.imageExtension');

imageFiles will be a structure that contains all the image file names in imageFiles(i).name.

thanks for your valuable answer Joseph Cheng..!!! from your answer iam able to store the images in an array...but can you please tell me how to acess that array..ie for example i want to generate iris templates from each image.. for one image i have function

        [template mask]=createiristemplate('image1.jpg');

if i want to create templates for all the images in that array,how should i access that array..

[Joseph Cheng]

you would write a for loop that cycles through the structure.

for i =1:length(imageFiles)
     filepath = [folder '\' imageFiles(i).name];
     [template mask]=createiristemplate(filepath);
end

I'll leave it to you to store the template and mask as i do not know the shape of the output of your createiristemplate.

however you could use structures.

       DATA(i).name = imageFiles(i).name;
       [DATA(i).template DATA(i).mask]=createiristemplate(filepath);

and store the data that way.
