契约

  1. Matrix4 initializes as a 4x4 identity matrix with 16 elements in column-major layout and isMatrix4 set to true
  2. set populates elements from 16 row-major arguments into column-major storage layout
  3. makeTranslation, makeRotationAxis, and makeScale construct affine transformations in homogeneous coordinates
  4. multiplyMatrices, multiply, and premultiply perform 4x4 matrix multiplication preserving associative transformation composition
  5. determinant computes 4x4 scalar determinant and invert calculates the inverse matrix restoring identity
  6. compose constructs a transformation matrix from position, quaternion, and scale, while decompose extracts them back
  7. lookAt constructs a view matrix pointing from eye position to target vector with specified up orientation
  8. transpose reflects matrix elements across the main diagonal and setPosition updates translation components
