Since you use diff(diff(...)), I suspect you want to solve differential equations, not algebraic equations.

If this is the case, use "dsolve" instead of "solve".

If no explicit solution can be found, integrate your equations numerically (e.g. using ODE45).

Which problem ? I can't execute your Matlab code ...
