This is a graphical matrix calculator developed using modern C++23 and Qt 6. It offers a rich set of matrix operations, from basic addition, subtraction, and multiplication to advanced functions like inverse, eigenvalues, and solving systems of linear equations. It is designed to facilitate the study and research of linear algebra.
This project implements a variety of core matrix operations:
- Supports 2 calculation types: floating-point numbers (double) and rational numbers, which can be switched in the top-left corner of the interface.
- Matrix Addition (A + B)
- Matrix Subtraction (A - B)
- Matrix Multiplication (A * B)
- Determinant (det(A))
- Inverse (inv(A))
- Eigenvalues (lambda(A))
- Adjugate Matrix (adj(A))
- Rank (rank(A))
- Trace (trace(A))
- Row Echelon Form (ref(A))
- Reduced Row Echelon Form (rref(A))
- Solve homogeneous systems of linear equations
Ax = 0 - Solve non-homogeneous systems of linear equations
Ax = b
- Core Language: C++23
- GUI Framework: Qt 6
- Development Environment: Visual Studio 2026 Insiders
- C++23 Compiler: This project is developed with Visual Studio 2026 Insiders. The latest version of Visual Studio 2026 Insiders is recommended.
- Qt Development Environment: This project depends on a statically compiled Qt 6 library. This means you need to either build Qt from source with the
-staticconfiguration option yourself, or obtain a pre-built static version for your environment. - Qt VS Tools: In Visual Studio's "Extensions" menu, search for and install the
Qt Visual Studio Toolsextension. Ensure it is correctly configured with the path to your Qt installation.
Note: The
.gitignorefile in this repository is the default one generated by Visual Studio and may not include intermediate files generated by the Qt build system (e.g.,moc_,ui_).

This project uses the open-source version of the Qt framework (LGPLv3) and links to it statically. According to the LGPLv3 license requirements, when distributing an application in this manner, you must provide the end-user with a way to re-link the application with a modified version of the Qt library. This can be achieved, for example, by providing your application's object files (.obj).
