Once we have defined the symbolic variables, we can use the built-in symbolic functions to perform operations and calculate derivatives. The most commonly used function for symbolic differentiation isdiff. This function takes the derivative of an expression with respect to a specified variable. For ...
MATLAB Online에서 열기 Add the variable "dens_mix" as an algebraic equation to your system (e.g. as y(13)): dydz(13) = y(13) - (partial_dens(1)+partial_dens(2)+partial_dens(3)+partial_dens(4)); and supply the mass matrix of your ODE system as ...
