i am plotting a mathematical code phi_u given in attached file i observed that values of o and p are changing w.r.t x but values of t is keep coming constant sames goes to e and f are changing but g coming constant because of this phi1 and phi2 are constant and so phi_u is constant and i am getting a straight line. how this can be done so that phi_u vary w.r.t x?
one more thing if i use u*u or x*x in expression i get the error inner matrix dimension must be agree so i used power(u,2) why this
