Hello:
A transformation matrix is given by K as :
___ 1 2 0
K = 0 1 0
___0 0 1

Draw a square in the R2 panel with the coordinates:
A: 0,0
B: 1,0
C: 1,1
D: 0,1

Which is like this:

Now use the transformation matrix K on all four coordiantes (A,B,C and D). Now draw the sqaure again with the new coordiantes.

Any suggestions on how I shall use the K on coordinate A?
Edit: Have a feeling that I am moving the square by (1,1) and also scaling the x-axis by 2, doubling it?
Edit2: Which means I am moving A from (0,0) to (1,1) then doubling the x-axis which makes A located at (2,1) after the transformation is performed, right or wrong? It isnt that simple? hmm..
