Hi,
I need to rotate a plot (airfoil for an aircraft) around its leading edge.

See graph:

The original plot is blue, and the rotation plot is red. The plot is rotated clockwise around the furthest left point (0,0) depending on a given angle.

What do you suggest? I was thinking that I need to come up with some sort of rotation matrix, but I don't know for certain how...

Thanks
