Re: generated wrapper code contains errors in arrays of dimension > 2

Hi Aidan

You need to write a typemap for this. Copy and modify the
SWIGTYPE[ANY][ANY] typemaps for what you want.

Editing code by hand is never ideal. Alternative workaround is to ignore
the variable with %ignore and add in some C getters/setters which will wrap
using default typemaps:

%inline %{
void setX(int i, int j, int k, double val) {
  X[i][j][k] = val;
}
void getX(int i, int j, int k) {
  return X[i][j][k];
}
%}
