addScaledOuterProductInPlace Method

Add scaled values from an outer product of vectors U and V.

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