problem converting a function

Hello, i have a system of symbolic equation which i need to solve, so i tried to solve it using this function: my_dif = mydifffunction2; g = matlabFunction(my_dif); h = my_vectorize(g); fsolve(h,[0.2,0.3,0.4,0.5])

where my diff function is an array of symbolic variables and my_vectorize converts it usinf num2cell the problem is i had the same value stored in an array as: 0.2672 0.2672 0.2672 0.4189 which doesn't make any sense, can anybody help?? thanks in advance
