It seems you’re looking for materials related to plotting an ( N \times N ) matrix in MATLAB, generating PDF outputs, and possibly free downloadable resources (like a tutorial paper or guide).
Below is a structured, helpful mini-guide that covers exactly these topics — functioning as a "paper" you can save as a PDF for free.

MATLAB includes free PDF export capabilities (no extra toolbox required).
An XnXn matrix is a square matrix with (n) rows and (n) columns. Here's a basic example of how to create and visualize an XnXn matrix in MATLAB. Let's assume (n = 5). It seems you’re looking for materials related to
