Hi Rony
An excellent attempt indeed! I can't say it is wrong except that you have not used the 2 single digit numbers as required of the riddle.
The extremely powerful Matlab application should solve the problem in no more than 5 minutes. On the other hand, try a conventional method using the Excel Solver. It may take about 12 to 15 minutes to solve it.
Some relevant clues here. The 2 single digit numbers are 3 and 5. The highest number used is 46. Four numbers are in their 10's; four in the 20's; four in the 30's and two in the 40's. The numbers occupying the four corners are 3, 22, 35 and 38. These clues are for only one method. There is at least another method that is quite universal.
Good luck pal.
Cheers!
