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, use
solve, and for numerical
vpasolve. For solving linear equations,
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).
