## @tomleslie  Thank very much you fo...

Thank very much you for answer.

I think the code will help me. Do you Know how can put all in one matrix?

i.e [M1,M2,....]

## @John Fredsted  Thank very much yo...

Thank very much you for answer.

I think the code will help me. But when I tried to find f(4,4) or f(8,8) I didn't get a matrix like f(2,2). Do Know what the problem?.

## loop of two variables...

This code can't help me because I am not looking for summing. I want expand the perivious  formula as I did for one dimension.

P[T]:=matrix(15,1,[p[0,14],p[1,14],p[2,14],p[3,14],p[4,14],p[5,14],p[6,14],p[7,14],p[8,14],p[9,14],p[10,14],p[11,14],p[12,14],p[13,14],p[14,14]]);

## @nm I want expand the formula for m...

I want expand the formula for i& j, i.e. i=j:=1 to 10, where m, n are fixed number (say m=n=10)

## product of matrix...

Thanks a lot for your reply and explain, I add the command it is run but the results, not in stander matrix form.

Also, the product ( last step) don't give an answer. I do another programme but in small size , it is doing well.

Thank  you again

## without space...

Thanks a lot for your reply, I remove the space but I have the same problem.

## the second form...

Thank you very much for your answer, I checked the system I have 30 equation with 30 variable.

I don't intend Eq[1,1]=0.

My problem I solved this system twice, just I change a number in Eq2. One of them gave   a solution but the other didn't give .

## A complex solution...

Thank you very much for your reply , when I add the option complex I get a complex solution and I looking for a real solution .

Thank you very much

## done when i change number...

Thank you for your reply,I don't Kown the exact solution for this system, just numerical solution.

Acutely I solved this system twice , one of them I get a solution. I attached it here.

So I don't What this mean ?!. Is this mean the system can't solve by own method ?.

Thank you very much

San.

## interface (....) and Matrix inverse...

@Kitonum

Thanks a lot for your help.

I do the same process for another example, all steps run without use this command (interface...). But in this example,  the matrix inverse doesn't run. I don't Know why I use maple 18.

Here I attached the other  example.

## @acer  Thanks a lot for your help&n...
