Hello all, I have a small problem with COMSOL. I am trying to use the particle tracing feature, more precisely I want to use the boundary coordinates to specify where are the points from which to trace the electrons. From what I understand in the User's Giude, the Boundary Coordinates feature...

Yeah, I looked everywhere in the documentation. There is nothing about special cases or anything like that. If there is something going on then I don't know what to do. I hope someone on this forum knows.

This is what MathCad says about their lsolve: lsolve(M, v) Returns the solution x for the linear system of equations M·x = v, using LU decomposition. The BLAS/LAPACK libraries (http://www.intel.com/software/products/mkl/features/lin_alg.htm ) from Intel are used. Arguments: M is a real or...

Hi everybody, Last time I was here I was asking about finding roots but many things have progressed. Anyway I have another problem now. I have a linear system of equations which I'd like to solve: A.X==B And I tried two things: get the inverse of A and multiply it with B and also use...

Thank you very much for your reply. This is exactly what I want to do. My programming experience is in the likes of Matlab and fortran. I am not used to this sort of structure but I a learning by doing. Again thanks again.

Hi guys and girls of physics forums, I have just created my account here and so this is my first post and I would like to appologise if my question may have been posted by someone else. I am new to mathematica but I am very found of the program. So much so that I am trying to use it for...
