This function plots a locational Gini curve following Krugman from regions - industries matrices.

1 | ```
locational.Gini.curve(mat, pdf = FALSE)
``` |

`mat` |
An incidence matrix with regions in rows and industries in columns. The input can also be a vector of industrial regional count (a matrix with n regions in rows and a single column). |

`pdf` |
Logical; shall a pdf be saved to your current working directory? Defaults to FALSE. If set to TRUE, a pdf with all locational Gini curves will be compiled and saved to your current working directory. |

`pop` |
A vector of population regional count |
