Matrix for C++

A tiny C++20 general-purpose library for dense, fixed-size and dynamically-sized matrices with no dependencies (other than std). It makes use of C++20s concepts to enable special features such as norm for vectors and many more.

Overview

Features:

intuitive syntax
low-overhead
header-only and single-header
fully constexpr (except where math functions like sqrt are used).
STL-oriented
Statically-sized have static memory (e.g. suited for audio development).
Dynamically-sized matrices are now available as well.
simple software design in comparison to some other matrix libs, e.g. no CRTP, virtual functions, ...
fully tested. Tests can be run with Catch2.

Limitations:

only C++20 (and up) because of heavy use of concepts and constexpr
this is not a linear algebra library - at the moment the library provides no linear algebra algorithms such as decomposition and solvers (exception: determinant and inverse of 2×2 and 3×3 matrices).

Supported Platforms

Since this repository uses C++20 language features, a fairly new C++ compiler is necessary.

Platform	Compiler	Minimum version
Windows	MSVC	14.30
Linux	GCC	13
	Clang	15
MacOS	AppleClang	15

Classes

Class	Definition
`Matrix<T,m,n>`	Main class for `m`×`n` matrices of type `T`
`Matrix_view<T>`	Matrix view class for viewing or modifying parts of a matrix like a block, row or column.
`Matrix_iterator<T>`	Random access iterator for iterating through a contiguous array in memory (matrix data).
`Matrix_stride_iterator<T>`	Random access iterator for iterating i.e. vertically through a contiguous array in memory.
`Matrix_block_iterator<T>`	Bi-directional iterator for iterating through a matrix block within a bigger matrix.
