# Equation Solving

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).
