Hai all, I am new to lapackpp. I want to do a curve fitting module ad part of my academic project. I want to solve a linear equation system having 100 different linear equations each with 100 unknowns. Can any one provide some sample code or documentation link for this. -- with warm regards Sivahari Nandakumar Appropriate Technology Promotion Society Eroor, Vyttila 09446582917 http://sivaharicec.blogspot.com -------------------------------------------------------- fighting for knowledge freedom |

Hi Sivahari, here's a small example I just have hacked: #include <iostream> #include <gmd.h> #include <laslv.h> int main() { // create left side LaGenMatDouble A(2,2); A(0,0)=1.0; A(0,1)=2.0; A(1,0)=0.0; A(1,1)=-1.0; // create right side LaGenMatDouble B(2,1); B(0,0)=0.0; B(1,0)=1.0; // Solve A*X = B LaGenMatDouble X(2,1); LaLinearSolve( A, X, B ); std::cout << A << " * " << std::endl << X << " = " << std::endl << B << std::endl; return 0; } I hope I understood your problem correctly, but I think you only need to create A(100,100) and fill in your values.

Thank you Dee, I will try and ping back. --Sivahari 2014-02-28 23:55 GMT+05:30 Dee <de...@de...>: > Hi Sivahari, > > here's a small example I just have hacked: > > #include <iostream> > #include <gmd.h> > #include <laslv.h> > > int main() > { > // create left side > LaGenMatDouble A(2,2); > A(0,0)=1.0; > A(0,1)=2.0; > A(1,0)=0.0; > A(1,1)=-1.0; > > // create right side > LaGenMatDouble B(2,1); > B(0,0)=0.0; > B(1,0)=1.0; > > // Solve A*X = B > LaGenMatDouble X(2,1); > LaLinearSolve( A, X, B ); > > std::cout << A << " * " << std::endl > << X << " = " << std::endl > << B << std::endl; > > return 0; > } > > I hope I understood your problem correctly, but I think you only need to > create A(100,100) and fill in your values. > > Best regards > Dominik > > > Am 28.02.2014 09:45, schrieb Sivahari Nandakumar: > > Hai all, > > > > I am new to lapackpp. I want to do a curve fitting module ad part of my > > academic project.

hai Dominik, It worked well, thank you. Is there any class in lapackpp deals with curve fitting? --Sivahari 2014-03-03 15:08 GMT+05:30 Sivahari Nandakumar <siv...@gm...>: > hai Dominik, > > It worked well, thank you.

Hello Sivahari, not that I'm aware of. I have programmed it manually in my Ph.D. thesis with the help of lapackpp. That means I got my input parameters, created a Least-Square matrix, solved it and extract the values for my line/polynom/spline (the latter in my case).
