addScaledOuterProductInPlace Method

add scaled values from an outer product.

  • The scaled outer product is a "rank 1" matrix.
  • This is useful in constructing mirrors and directional scales.
    A+=s[UxUyUz][Vx Vy Vz][Axx Axy AxzAyx Ayy AyzAzx Azy Azz]+=s[Ux∗VxUy∗VxUz∗VxUx∗VyUy∗VyUz∗VyUx∗VzUy∗VzUz∗Vz]A += s \columnSubXYZ{U}\rowSubXYZ{V}
\\ \matrixXY{A} += s \begin{bmatrix}
U_x * V_x & U_y * V_x & U_z * V_x \\
U_x * V_y & U_y * V_y & U_z * V_y \\
U_x * V_z & U_y * V_z & U_z * V_z \end{bmatrix}
