Hi Nasser,
Thanks by the attention, but I did not understand your solution... I tried now to apply that at MatLab and it did not work !

My necessity is to solve  the system below (to find H)  :

IMPORTANT : H is a 3x3 matrix. Thus, I have nine unknows.

H = [ h11 h12 h13 ; h21 h22 h23 ; h31 h32 h33 ]

[296 199 1]' = H * [0.1 0.1 1]'
[367 210 1]' = H * [0.2 0.1 1]'
[273 267 1]' = H * [0.1 0.2 1]'
[346 281 1]' = H * [0.2 0.2 1]'

How should I use your proposition A\b ?

Thanks,

Carlos
