Matrix & Vector

Geometry

For small, fixed size vectors & matrices, as typically used in geometry (i.e. 2D, 3D, 4D).

Vector2<T = Float>
Vector3<T = Float>
Vector4<T = Float>

Vector<Int size, T = Float>  // as base class

Matrix22<T = Float>
Matrix33<T = Float>
Matrix44<T = Float>

Matrix<Int rows, Int columns, T = Float>  // as base class

Using the namespace cilia::geometry to avoid naming conflicts, but Vector2/3/4 could still be (also) in namespace cilia.

Linear Algebra

For large, dynamically sized vectors & matrices, as typically used in linear algebra (i.e. BLAS – Basic Linear Algebra Subprograms), in the namespace cilia::linalg.

Vector<T = Float>
Matrix<T = Float>

Column-Major

Matrices (unlike images) are stored column-major, like:

0 3 6
1 4 7
2 5 8

Datatype & Precision

The default datatype is Float (with 64-bit precision), which is well suited for scientific calculations.

Feel free to define your own type aliases:
