MATLAB: Pixel value in given direction

Question

Dear all,

Let say I have point at location (x1, y1). I want to get an other point (x2, y2) at the distance of d pixel in the direction of T, where T is an angle.

Or let say I have circle with radius d with center point (x,y), I want to get an other point at the distance d from center (x,y) in the direction of T.

Answer 1

let say you want to get point (x2,y2) then

x2 = x1 + d * cos(T);
y2 = y1 + d * sin(T);

I hope this is what you wanted.
