F =
Hi Gokhan,
I have tried this code in R2024a, it is working fine.
clear all
clc
syms a b c d m n s r x y k
dy1 = -x*( r*x.^2 - r*(a+b)*x + a*b +(c*y-r*d));
dy2 = s + m*x-n*y ;
dr = r-x;
F=[dy1;dy2;dr]
% equilibrium_points = solve(F == 0, [x, y, r]);
% equilibrium_points = ...,
% [equilibrium_points.x, equilibrium_points.y, equilibrium_points.r];
J=jacobian(F,[x y r])
“clear” – Removes variables from the workspace, but does not clear functions, global variables, or MEX files from the memory.
“clear all” – Removes all variables, functions, and MEX files from the memory, resetting MATLAB to a clean state.
Use the following command to know if there are multiple variables defined with same name at different locations:
which J -all
