Histogram computation from gradient image.

Hello everyone
I want to compute the histogram using image gradient.let say that I have an image
Img=imread(myimage);
[gx gy]=edge(Img,'sobel');
Mag=sqrt(gx,gy);
Dir=atan2(gy,gx);
now I want to compute the orientation bins using 12 orientations each covering 30degree.
how can I do it.After that I need to sum(Img,Dir) from 1 to number of bins 12.
Any help is appreciated.
