nicematrix – Matrices with continuous dotted lines drawn with TikZ

This pack­age pro­vides new en­vi­ron­ments NiceMa­trix, pNiceMa­trix, bNiceMa­trix, etc. sim­i­lar to the clas­si­cal en­vi­ron­nements ma­trix, pma­trix, bma­trix, etc. of math­tools.

In these new en­vi­ron­ments, new com­mands \Cdots, \Vdots, \Ddots, etc. are avail­able to draw con­tin­u­ous dot­ted lines from two cells of the ma­trix. The re­sult is more aes­thetic than the clas­si­cal re­sult ob­tained us­ing \cdots, \vdots, \ddots, etc. The con­tin­u­ous dot­ted lines are drawn with TikZ.

It is also pos­si­ble to use this pack­age in a trans­par­ent mode where the clas­si­cal en­vi­ron­ments ma­trix, pma­trix, etc. are re­de­fined in such a way that \cdots, \vdots, \ddots, etc. draw the con­tin­u­ous dot­ted lines au­to­mat­i­cally.
