This is about linear systems with fewer equations than variables; A*x = b where the m -by- n matrix A has fewer rows that columns, so m < n . I have always called such systems wide or fat, but this is not respectful. So I consulted the Merriam-Webster Thesaurus and found commodious (https://www.merriam-webster.com/dictionary/commodious#synonym-discussion).

This is also one my first posts to use the Live Editor™. Here is a a link (https://blogs.mathworks.com/cleve/files/commodious_blog.mlx) to the .mlx file.
