You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: computeDeblur.m
    path of file: ./repos/OMEGA/source
    
    the code of the file until where you have to start completion: function im_vectors = computeDeblur(im_vectors, options, iter, gaussK, Nx, Ny, Nz)
%COMPUTEDEBLUR Computes the PSF deblurring phase for all selected OS

    
function im_vectors = computeDeblur(im_vectors, options, iter, gaussK, Nx, Ny, Nz)
%COMPUTEDEBLUR Computes the PSF deblurring phase for all selected OS
%algorithms

if options.save_iter
    iter_n = iter;
else
    iter_n = 0;
end
