I open a new subject about Fredholm Integral equation. My code work correctly.
But, I need some modification to get a nice display of the matrix found using
MatA,Vectb := GenerateMatrix(convert(sys3,list),Sol_phi);
such as Sol_phi is my solution that I want to find.
I introduced two function alpha1 and alpha2 in the code see Equation (9) can I write all the coeficient of my matrix using the two function alpha and alpha, it's better to see and read the matrix form.
