Hi All,

I have to integrate over an domain that is discrsized with many tri-angular elements, and i have to take the integration over every sub-trielement, so do you know if there are some matlab code to caculate the coordinates of Gaussian quadrature point over a triangular when the three vertices are given?

Thanks a lot.
