@Carl Love Thank you so much!.

Maple noticed "error"

@vv Sorry, all of you. I don't know how to create a matrix which have det=2. I don't understand

@acer Thank you very much

@tomleslie How thoughtful.Thank you very much!

@Thomas Richard Yes. That is Cholesky decomposition. You see, Ly=b, Transpose(L)x=y, Maple notice "error". I don't understand. Can you explaint it to me? Thank you so much!

@acer Thank you very much!

@tomleslie Thank you so much!

@Carl Love Thanks for your help! 

@Carl Love Thank you so much! :D 


Thank you so much! 


local  i,j, n, Q;  



P:=array(0..n,[]);  j:=0;  

for i to n+1 do      

Q[i-1, j]:=op(i,Y);      

P[i-1]:=op(i,X);  od;

 for i to n do  

    for j to i do    

   Q[i,j]:=((x-X[i-j))*Q[i,j-1]-(x-X[i])*Q[i-1,j-1])/(X[i]-X[i-j]);        od;  od;

 for i from 0 to n do      


for j from 0 to i do    

    printf("%f",Q[i,j]);  od;  

printf("\\n");  od;  end proc:

I writed but I don't know errors

@Preben Alsholm Thank you so much

@tomleslie Thank you so much!

@Carl Love  Thank you very much! :D
