Solving Commodious Linear Systems - Cleve Moler on Mathematics and Computing

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 [URL="https://www.merriam-webster.com/dictionary/commodious#synonym-discussion"]commodious[/URL].

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