I have about 3000 .raw images in a folder.

I need to open them all and convert in to matrix form and then do mean and standard deviation

to convert 1 image I have a function that works like this:

img1=openraw ('C\path\folder\img00001.raw')

how can I make it so that the loop will open all of them? I cannot see a way to make the path of the image part of the loop so that for example:

starting point: C\path\folder\img00001.raw

loop 1: C\path\folder\img00002.raw

loop2: C\path\folder\img00003.raw

etc etc.

please help

thanks!

   F = dir('C\path\folder\*.raw');
   for ii = 1:length(F)
      imagesAll(:,:,ii) = openraw(F(ii).name);
   end

But you have to be careful in image size. If they are not equal than you have to make them equal. Otherwise the matrix will give you an error.
