Change the name of the output file as a loop computes

Hello all,

What i want to do is create a stack of files... i have a function F(x,y,z) and it is set to run and calculate F at different z values something like:

for zloop=1:pixel_dimension;
    z=zloop; 

      calculate the function based on x y and the changing z value F(x,y,z)

      PSF=(abs(F)).^2;

% save images

imwrite(PSF, 'C:\Documents and Settings\User\My Documents\MATLAB\Deconvolution\Brenden\Deconvolution\Point Spread Function\PSF stack\   NAME   .bmp', 'bmp');

end

What i want to know is how to change the name of the output file with each iteration so i dont "write over" the same file each time.

for zloop=1:pixel_dimension;
    z=zloop; 
      calculate the function based on x y and the changing z value F(x,y,z)
      PSF=(abs(F)).^2;
% save images
imwrite(PSF, ['C:\Documents and Settings\User\My Documents\MATLAB\Deconvolution\Brenden\Deconvolution\Point Spread Function\PSF stack\' num2str(zloop) '.bmp'], 'bmp');
end

can i add more to the name than just the number zloop?? like name it PSF(zloop)??

just be careful not to add something that the OS won't allow for file names

[path string1 string2 ...]

As the file input, create a string with the file name. For example,

filename = ['file',num2str(zloop),''];
