Warning: Unable to find symbolic solution. disp = matlabFunction(sol); 2 Comments Dyuman Joshi on 23 May 2023 Edited: Dyuman Joshi on 23 May 2023 Open in MATLAB Online Ran in: Deinfe FgE and FgM as symbolic expressions instead of function handles. Even after that the ode doesn't...
I am trying to solve a second order ODE in matlab. But I keep getting the error: Unable to find a symbolic solution. How do I rectify this error? ThemeCopy syms C(Z) DC = diff(C); ode = diff(C,Z,2) == (phi^2)*C*exp(gamma*beta*(1-C)/(1+beta*(1-C))); Zspan = ...
