Simulink provides two fixed-step implicit solvers: ode14x and ode1be. This solver uses a combination of Newton's method and extrapolation from the current value to compute the value of a state at the next time step. You can specify the number of Newton's method iterations and the extrapolation ... Witryna19 sie 2015 · In Matlab, I am trying to solve an implicit function, see the following: Cp = Cpi / ( sqrt(1 - M^2) + (M^2 / (sqrt(1-M^2))) * Cpi/2 ) Here, I know the values of both M and Cp and want to know the value of Cpi. Also, due to computational time considerations, I would like to avoid using loops in the approach. teams email log in
