Only linear transformations are possible with transformation matrices
(scales, rotates and translates are just shortcuts to equivalent
transformation matrices).
  What you are trying to achieve is a non-linear transformation which
is not possible with matrices.

  The way to go is most probably to create the cone as an isosurface
and then modify the input variables of the isosurface function
appropriately.
