C/C++ How to calculate rotation, divergence in C/C++

Click For Summary
The discussion focuses on creating a C/C++ program to calculate the divergence and rotation of vector fields, particularly in the context of electromagnetic fields. It highlights the challenge of implementing mathematical operations in C++, as the language does not natively support vector objects. A suggestion is made to create a "Vector" class and define necessary operators for divergence and curl. Additionally, the uBLAS library from Boost is recommended as a potential resource. The conversation also notes that while numerical differentiation can be implemented in C++, it may require additional research to effectively execute.

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.
