You can solve algebraic equations, differential equations, and differential algebraic equations (DAEs).
Solve algebraic equations to get either exact
analytic solutions or high-precision numeric solutions. For analytic solutions,
solve, and for numerical solutions, use
vpasolve. For solving linear equations, use
linsolve. These solver functions have the flexibility to
handle complicated problems. See Troubleshoot Equation Solutions from solve Function.
Solve differential algebraic equations (DAEs)
by first reducing their differential index to
0 using Symbolic Math Toolbox™ functions, and then using MATLAB® solvers, such as
ode23t. See Solve Differential Algebraic Equations (DAEs).
