accelerate 3D matrix multiptication using bsxfun

I have athe following code
it takes forever to run, and disable my CPU in the prosess…
I’m looking for a way to make it run better (GPU is also an option)
norm_mode is 256×256 double matrix (X,Y) image
fields is 16384×15 complex double matrix (time,mode)
in the end’ I need a 3D matrix take each norm_mode image will also be a function for time and suming all the modes- 3D matrix 256x256x16384
that is the total_field

do you have any sugestions on how to make it run better?

Thanks,
Barak
function total_field = BuildSpatialField(fields,fiber, sim, others)

total_field = zeros( newSize, newSize, length(others.t) ); % total_field(X,Y,t)

h = waitbar(0, ‘calculate field…’);

for ii=1:others.modes

norm_mode = % load new phi

tmp = bsxfun(@times, norm_mode, reshape(fields(:,ii),1,1,[]));

total_field = total_field + tmp;

waitbar(ii/others.modes, h, [‘mode ‘ num2str(ii) ‘ from ‘ num2str(others.modes)]);

end
close(h);
