Shows what matrices *A, b* look like as the system of linear equations, *A x = b* with three unknowns,
x1, x2, and x3, by plotting a plane for each equation.

1 2 3 |

`A` |
either the matrix of coefficients of a system of linear equations, or the matrix |

`b` |
if supplied, the vector of constants on the right hand side of the equations, of length matching
the number of rows of |

`vars` |
a numeric or character vector of names of the variables.
If supplied, the length must be equal to the number of unknowns in the equations.
The default is |

`xlim` |
axis limits for the first variable |

`ylim` |
axis limits for the second variable |

`zlim` |
horizontal axis limits for the second variable; if missing, |

`col` |
scalar or vector of colors for the lines, recycled as necessary |

`alpha` |
transparency applied to each plane |

`labels` |
logical, or a vector of character labels for the equations; not yet implemented. |

`solution` |
logical; should the solution point for all equations be marked (if possible) |

`axes` |
logical; whether to frame the plot with coordinate axes |

`lit` |
logical, specifying if lighting calculation should take place on geometry; see |

nothing; used for the side effect of making a plot
