a = 1 : len
xoff(a) =Cxy(a,1) - Cxy1(a,1)
yoff(a) = Cxy(a,2) - Cxy1(a,2)
XYD(a) = sqrt(xoff(a).^2 + yoff(a).^2)

this the code which i am trying a = 1 : len xoff(a) =Cxy(a,1) - Cxy1(a,1) ; yoff(a) = Cxy(a,2) - Cxy1(a,2); XYD(a) = sqrt(xoff(a).^2 + yoff(a).^2);

I haven't the slightest idea what that sentence is trying to describe even after reading it several time. Perhaps you can attach a diagram or have another English speaker try to phrase it better. As of now, all I can suggest as a wild guess is to use improfile(), imdistline(), or use sqrt() and the Pythagorean Theorem. Or perhaps use pdist2() in the Stats toolbox.

Hi everyone can anyone help me please i want to subtract these two matrices the same number of element in matrix
xy=[125 133 0 0 0 0 0 0 0 0 0 0 0 0 ; 50 65 0 0 0 0 0 0 0 0 0 0 0 0]
x1y1=[0 0 0 0 0 0 102 0 0 0 0 120 0 0; 0 0 0 0 0 0 63 0 0 0 0 45 0 0]

Regarding your "Answer"
"Hi everyone can anyone help me please i want to subtract these two matrices the same number of element in matrix
xy=[125 133 0 0 0 0 0 0 0 0 0 0 0 0 ; 50 65 0 0 0 0 0 0 0 0 0 0 0 0]
x1y1=[0 0 0 0 0 0 102 0 0 0 0 120 0 0; 0 0 0 0 0 0 63 0 0 0 0 45 0 0]
"
Did you try the obvious:
difference = xy - x1y1
