Plus using constraints to minimize wrong guess.
It solved well defined sudoku puzzles in about 3 sec in my Matlab.

To create puzzle, use syntax s{r,c}=value. for all r,c,value=1~9.
for example, s{1,4}=5;

The submission attaches two examples for demo.

To see each move during solving, comment off show(s) in the function move at line 54.
