elements to vertices

Anne_st

I get area of each element using function GetAreas(md.mesh.elements,md.mesh.x,md.mesh.y), now I want to use area weighting to compute misfit ,such as velocity misfit, however velocity is in vertices, the number of area and velocity is not equal, I can't mutily them dirctly. How to convert areas(with number of elements) to vertice?

Hi @Anne_st

the easiest may be to take the average misfit for each element? If you have a vector misfit that is of size md.mesh.numberofvertices, you can do this:

misfit_elements = mean(misfit(md.mesh.numberofelements),2);
integrated_misfit = sum(misfit_elements.*areas);

I hope this helps!
