A 3x3 matrix, row-major: _11 to _33, also v[row] as Vector3 rows, coef[row][col] and floats[9]. Matrix3 * Vector3 multiplies by a column vector, Matrix3 * Matrix3 is the product, and +, - and * float work element by element. A rotation matrix of a quaternion is made by rotation_matrix(Matrix3, q).
m := Matrix3_Identity;
m._13 = 5; // row 1, column 3
assert(m.v[0] == xyz(1, 0, 5) && m.coef[0][2] == 5 && m.floats[2] == 5);
assert(m * xyz(1, 1, 1) == xyz(6, 1, 1));Fields
