### Exercise 4, Q1b

Hi,

we think there is an error in the starting kit of exercise 4 in question 4b.

In line 22 there is a conversion from homogeneous to cartesian and back,

Code: Alles auswählen

cart2hom(hom2cart(squares));

Since the coordinates of "squares" are in cartesian, this call is in the wrong way round we think.

Best regards

Yes indeed, since the matrix squares stores cartesian coordinates, the call is the wrong way round.
Nevertheless the result of the line is nowhere used.

I am sorry for this inconvenience. I hope the line did not confuse somebody.
