i am working with MuPAD. I can make vectorfields in 3D and also Surfaces in 3D via plot::VectorField3D and plot::Surface.
But now i want to draw a vectorfield ON a surface. If $X$ is a vectorfield and $\sigma$ a parametization of a surface $S$ then we can have a look to $X\circ\sigma$. This gives a vectorfield on $S$. But this can not be done with MuPAD, true?
Can someone help me with this problem or can someone explain how to draw such a vectorfield i am searching for?!
Thank you.
Search bunch and read the associated code in this (the normal vector field can be replaced by any one).
Does a command arrow exist in MuPad (as in Mathematica) ?
