One recent example of this was when they the first to report the fact that the <a href=\"https:\/\/uk.mathworks.com\/support\/bugreports\/details\/3501766\">svd function slowed down by orders of magnitude for tall-and-skinny or short-and-wide matrices on Apple Silicon<\/a>. They provided a short and clear demonstration of the issue that gave our developers a head-start in tracking down the underlying issue.
