[Cuis] Array2D newSize:

Maybe it's my dyslexia, but isn't this backward?

"Array2D newSize: 2 at 3" produces an array with 3 rows and 2 columns:
| nil nil |
| nil nil |
| nil nil |

IMO it should be:
| nil nil nil |
| nil nil nil |

For example, in Squeak, "MatrixTransform2x3 identity" produces:
MatrixTransform2x3(
1.0	0.0	0.0
0.0	1.0	0.0
)

Please correct me if I'm wrong.

OK, you're wrong - as long as there is a subclass called Matrix in

LinearAlgebra.pck.st

Use Matrix instead of Array2d.

(whew)
