Solve algebraic and differential equations

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
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 equations** by
using `dsolve`

. Create these
differential equations by using symbolic functions. See Create Symbolic Functions.

Solve **differential algebraic equations** (DAEs)
by first reducing their differential index to `1`

or `0`

using Symbolic Math Toolbox™ functions,
and then using MATLAB^{®} solvers, such as `ode15i`

, `ode15s`

,
or `ode23t`

. See Solve Differential Algebraic Equations (DAEs).
