Matrix mult result size; also cols A must equal rows B | |

Matrix transpose | |

Column vector representation | |

Symmetric matrix (X is be any value) | |

Antisymmetric matrix or skew-symmetric matrix (diagonals must be 0) | |

Column vector mult notation (a,b,c cols of M) | |

2D Matrix determinant | |

Recursive determinant (each is the sub matrix excluding the current col) | |

k is chosen as any row; good when row is mostly zeros | |

Cofactor matrix definition | |

Inverse; adjugate matrix | |

2D Matrix inverse | |

3D Matrix inverse | |

3D matrix inverse (a,b,c cols of M) | |

4D Matrix inverse. a,b,c,d = 3D column vectors of M. | |

x,y,z,w = last row of M, x = , t = , u = , v = |
