bond graph in matlab

To create a bond graph in MATLAB, you can use the "Symbolic Math Toolbox" which provides functions to represent and manipulate expressions symbolically. Here is an example code snippet to create a simple bond graph:

main.m
syms x1 x2 c1 c2

% Define the system dynamics
f1 = c1 * x1 - c2 * x2;  % Define the bond graph element 1
f2 = c2 * x2 - c1 * x1;  % Define the bond graph element 2

% Create the bond graph equations
eq1 = c1 * x1 - f1;
eq2 = c2 * x2 - f2;

% Solve the equations to get the equations of motion
solutions = solve([eq1, eq2], [x1, x2]);

% Display the solutions
disp(solutions);

In this code snippet, we first define the symbolic variables x1, x2, c1, and c2 representing state variables and parameters of the bond graph elements. Then we define the system dynamics in terms of these variables, create the bond graph equations, and solve them to obtain the equations of motion.

Remember to adjust the equations and variables based on the specific bond graph model you want to create.
