Hi all,

Does anyone knows how to calculate a triple integral in cylindrical
coordinates using triplequad? In which order must I give the limits?

In any order you wish?

You define the function to be called as a function
of its arguments. So you choose how the arguments
are defined, as well as their bounds. The burden
is on you to be consistent.

Do remember that a volume integral in cylindrical
coordinates will have volume element r*dr*dtheta*dz.
Don't forget the r.

HTH,
