Hi all,
Following is described of my question.
Suppose that, I have XY coordinate and 2 points (a,b)
Now, I create new XY coordinate with a is original point.
C is one point of x'ay' coordinate.
So, How to convert C position to xy coordinate??
or in opposite, if C is one point of xy coordinate, how to get position of C in x'y' coordinate??
Do anyone have idea, please help me.
Thank you so much.
