code: public Matrix4f setTranslation(float x, float y, float z) {
          this._m30(x);
          this._m31(y);

docs: Set only the translation components <code>(m30, m31, m32)</code> of this matrix to the given values <code>(x, y, z)</code>.
  <p>
  Note that this will only work properly for orthogonal matrices (without any perspective).

  To build a translation matrix instead, use {@link #translation(float, float, float)}.
  To apply a translation, use {@link #translate(float, float, float)}.
