Gaussian Elimination

Basic algorithms are implemented in C

• Solving a linear system by Gaussian Elimination without Pivoting
• LU - decomposition "in place" where L and U are placed directly in A
• A number of useful helper functions (norms, distances, creation and destruction of matrices, random matrix generation)

IDE - Emacs

The code and Makefile will work with Emacs, given that typical packages for C/C++ development are installed (GCC, GDB and GNU Make)

IDE - VSCode

The folder .vscode contains two files, launch.json and tasks.json which allow debugging with VSCode. Three extensions are needed. In addition, GCC, GDB and GNU Make must be installed.

Install the following VSCode extensions:

• C/C++ by Microsoft (for code editing and IntelliSense).
• Makefile Tools (for Makefile support).
• CodeLLDB (or C/C++ Extension Pack) for GDB-based debugging support.

Also, modify the paths to GCC and GDB in the file launch.json.
