SUMMARY

This discussion focuses on calculating divergence and rotation of vector fields using C/C++. The user seeks assistance in implementing these calculations, specifically highlighting the need for a custom "Vector" class to handle mathematical operations, as C++ lacks native support for such objects. The Boost uBLAS library is recommended as a resource for vector operations, while numerical differentiation techniques are noted as relatively straightforward to implement in C++. The conversation emphasizes the complexity of the task compared to higher-level languages like Matlab.

PREREQUISITES
  • Understanding of C++ programming and object-oriented design
  • Familiarity with vector mathematics and operations
  • Knowledge of numerical differentiation techniques
  • Experience with the Boost uBLAS library for linear algebra
NEXT STEPS
  • Implement a custom "Vector" class in C++ for mathematical operations
  • Explore the Boost uBLAS library for vector manipulation
  • Research numerical differentiation methods applicable in C++
  • Study the mathematical concepts of divergence and curl in vector calculus
USEFUL FOR

Software developers, particularly those working in scientific computing or physics simulations, as well as students learning about vector calculus and its applications in programming.

Dear Experts,

I started to look deeper into the electromagnetic fields.
So I would like to write a simple code in C/C++, which is capable of calculating the divergence or rotation of the vector fields.

Could someone helps me please, to get this started?
How to illustrate partial derivatives in the program?

I would be very grateful for your helps!

Unfortunately your program won't be very simple! Unlike a 4-th generation language such as Matlab, C++ does not natively support mathematical objects such as vectors. You'll need at least to write a "Vector" class, and define your operators (div, curl, etc) based on that.

You might be interested in the uBLAS library in Boost (www.boost.org).

Numerical differentiation is more or less straightforward in C++, Google should help you out with that.
