i found the gradient and magnitude with this code but i dont know how to find gradient orientation histogram.if u know help me
angle = 360;
[GradientX,GradientY] = gradient(double(img));
Gr = sqrt((GradientX.*GradientX)+(GradientY.*GradientY));
index = GradientX == 0;
GradientX(index) = 1e-5; YX = GradientY./GradientX;
A = ((atan2(GradientY,GradientX)+pi)*180)/pi;
