Solve system of differential equations - MATLAB dsolve
https://www.mathworks.com/help/symbolic/dsolve.html
Differential equation or system of equations, specified as a symbolic equation or a vector of symbolic equations. Specify a differential equation by using the == operator. If eqn is a symbolic expression (without the right side), the solver assumes that the right side is 0, and solves the equation eqn == 0.. In the equation, represent differentiation by using diff.
