Hello,
How do I calculate the radial displacement of a node on a cylinder from it's XYZ displacement. Center coordinate system sometimes is at center of the cylinder sometimes it's not. because I have more than one cylinder. I tried trignometry and the values does not make any sense. Below is the code I used. M\aybe what I need to calculate is the distance shown using the yellow line.
I have attached a sketch for reference. What am I missing here?

r=sqrt(bsxfun(@plus, bsxfun(@plus,x.^2,y.^2),z.^2 ));

THe solution
x1 = x + x_;
y1 = y + y_;
dr = sqrt(x1.^2+y1.^2) - r;
