how we can find intersection of sphere and cylinder????

hi i am new in programming . i have sphere x1^2+0.1*x2^2+x3^=1 and a cylinder x1^2+x3^2=1.4. how i can find intersection of these two surfaces.

Insert 1.4 for x1^2+x3^2 in the first equation and you'll see that the two surfaces do not intersect ...

I don't know whether MATLAB offers the possibility to deduce simpler equations for lower dimensional manifolds in IR^n that are given by a system of nonlinear equations. You may try MATLAB's "solve" command.
