How define the rotation of a rectangle in space ?

Hi All

I have a rectangular plan with the coordinates of its corners in space. this plane moves in space and does all the 6 dof moves, and I have all the coordinates at all times. how do I individualize and specify the rotation of this rectangle around its normal on the surface?

Let's suppose rect is the rectangular shape, you want to rotate it with 45 degrees (Anti-clockwise)-about z-axis

rot=rotate(rect,45,[0 0 0],[0 0 1])

As you mentioned its normal on the surface

This function introduced R2017a afterward

Thank you but I want to measure a given rotation, I don't want to rotate it
