I was following procedures for our experiment and symengine error occured.
G = (12*s^3 + 24*s^2 + 28*s + 9)/(2*(- 24*s^4 - 12*s^3 + 70*s^2 + 156*s + 99))
>> v_t = heaviside(t);
>> V_s = laplace(v_t);
>> Vc_s = G*V_s;
>> vc_t = ilaplace(Vc_s);
>> t = 0:.1:10;
>> vc_t = matlabFunction(vc_t);
Error using symengine
Code generation failed due to unexpected object of type
'RootOf'.

res = mupadmex('symobj::generateMATLAB',r.s,ano,spa,0);

r = mup2mat(c{1},true,sparseMat);

Is it required to find the symbolic solution and then evaulate it numerically? Or is it allowed to go straight to a numerical solution of vc_t?
