What is the correct way to name the namespaces in a project?

Question

C++ / C#

Tell me if there is any guide on how to properly name the namespace in the project.

Answer 1

Alternatively, by the names of modules in the project and their areas of responsibility.
Project->Module->...
For example,

namespace Matlab::LinearAlgebra::Matrix
{
}

Matrix - a namespace that contains classes for working with matrices, which is located in the Linear Algebra module of the Matlab project.
