Symbolic Math Toolbox™
The int function should work

[Walter Roberson]

The int() function should do a decent job if it is symbolic answers that are generally required. If it is numeric answers that are generally required, then the Symbolic toolbox does have numeric integration routines, but there are also numeric integration routines that are part of basic MATLAB without requiring the Symbolic Toolbox.
