Here's the complete example code:

MATLAB is a powerful tool for numerical computation and data visualization. When working with large datasets, it's often helpful to visualize the data in a matrix format. In this guide, we'll walk you through the steps to plot an nxn matrix in MATLAB and save it as a PDF file.

To plot the matrix, use the imagesc() function:

You can download a free PDF version of this guide: matrix_plot_guide.pdf

To save the plot as a PDF file, use the print() function:

imagesc(matrix); This will create a heatmap of the matrix.
