vecpp :: reference :: Mat<typename, std::size_t, std::size_t>

Mat<T, C, R> does not define a constructor per-se, but instead relies entirely on aggregate initialization.

default construction

Default-constructing a matrix will leave it in an undefined state.

N.B.

• Default-constructed matrices are not allowed in constexpr code, which is why you might see some Mat v = {}; within the vecpp codebase where default initialization would have made sense.

Examples:

using Mat2 = Mat<float, 2, 2>;

// default construction
Mat2 mat;

// value-construction
Mat2 identity = {
  1.0f, 0.0f, 
  0.0f, 1.0f
};

// copy-construction
Mat2 identity_copy = identity;
