Optimizing a rank 3 tensor $F$ is not Hermitian in $u$ and $v$. |

Optimizing a rank 3 tensor That's a wonderful answer!!! My paper will see the sun soon, and you will definitely be among the acknowledged people. Thanks a mil... |

Optimizing a rank 3 tensor I agree, but the way I would use to write the program would take days of typing, perhaps there is a concise way of writing down the matrix that you can code here! |

Optimizing a rank 3 tensor @whuber If you mean write all the equations down, like expand for all the indices, then we are talking about 64 equations, which, to me, doesn't sound practical. |

Optimizing a rank 3 tensor @whuber $i$ in the formulas is the imaginary unit. |

Optimizing a rank 3 tensor @whuber Thanks for the comment. I'm just providing 16 entries. Example F_1^i={F_1^1,F_1^2,F_1^3,F_1^4}, which represents the first column in the 4x4 matrix. |

Solving antisymmetric tensorial equation Is it possible to write the code in different way such that it takes less time. I've been running the program since yesterday and still waiting. I think its because my F entries are complicated function of space. Also If, say, we suppress the condition of S being symmetric in the lower indices, would that decrease the time cost? |

Solving antisymmetric tensorial equation Thanks for your answer, Mathematica is running now your code. Hope it works. I logged in with my google account, does it mean I'm registered or I have sign up differently? (sorry for the silly question). |

Solving antisymmetric tensorial equation @belisarius Thanks for your comments, I have a code that gives me $F$ which is an endomorphisms acting on the tangent space of some moduli space. I will update the questions with what I tried to do... |
