rectangle instead of square for camera calibration

I need to use a big checkerboard (36x36 in) for camera calibration with wide angle lens camera.

However, checkerboard is not perfectly square. The size of the square is x = 67.7 mm and y = 67.9mm.

My question is can we use the rectangle size x and y to do the calibration simply modify the code

worldPoints = generateCheckerboardPoints(boardSize, squareSize) to accommodate x, y?

Thanks, Bob

Unfortunately, this function does not support rectangle patterns.
