MATLAB MATLAB Central Community Advisory Board I'm delighted to announce that I have been invited to join the MATLAB Central Community Advisory Board (CAB). When I retired from MathWorks, almost a year ago, I knew that I wanted to stay involved with the MATLAB community. To that end, I have continued blogging about MATLAB
MATLAB Update Regarding Add-On Versioning My colleague Michelle Hirsch, from MathWorks, provided an update regarding yesterday's blog post about add-on versioning. MathWorks has new package version management features available, and they are working to extend that functionality to support code submissions on MATLAB File Exchange. See her full reply on MATLAB Discussions.
MATLAB Issues with Add-On Versioning I am making updates to one of my File Exchange add-ons, and the updates will require an updated version of another add-on. The state of versioning for add-ons seems to be a bit of a mess. First, there are several sources of truth for an add-on’s version: * The GitHub
Horn Where Musicians Live I was once looking around for demographics information about musicians, and I encountered this map, entitled "Which City Has the Most Musicians?" Source: Zippia.com At first glance, I thought the map was intriguing, and I started exploring it and wondering why musicians lived in certain places and
MATLAB The Story of TIMEIT The function timeit started out in an engineering textbook about image processing using MATLAB.
Horn My Latest Self-Recording Setup I decided to try a low-cost, portable option based on the RØDE Wireless GO II system.
MATLAB IMVIEW: A New Image Display Function I've been working on a new image display function that I intend to use instead of imshow.
MATLAB Function Syntax Design Conundrum I love using the arguments block, but it doesn't handle this use case well.
Combining My Blogs I started a blog about my French horn learning path and musicianship on hornjourney.com back in May 2023. Later, after retiring from MathWorks in March 2024, I started a second blog, on matrixvalues.com, about MATLAB and image processing in MATLAB. I've now decided to simplify my
Horn Octave Notation Change in The Horn Call The Horn Call has switched to a better notation for distinguishing pitches in different octaves.
MATLAB Pixel Grid Update As it turns out, there are several ways to draw thousands of line segments with just one "line" object.
MATLAB Image Zoom and Pan Utilities In today's world of display devices with a wide range of resolutions, this notion of a virtual pixel has evolved to help interface and website designers achieve reasonably consistent results on different devices.
MATLAB Cris Luengo on Image Processing Library Design Issues Cris Luengo discusses how the "everything is a class" design philosophy affects the complexity of the resulting client interfaces.
Horn Thinking Again About the Word "Amateur" "Amateur" in French always gives the connotation of someone who deeply appreciates and is knowledgeable about something.
MATLAB Step Through Your Code Although I was certainly happy to have found the bug before the feature shipped, I was disappointed to have found it fairly late in the development process.
MATLAB FFT Zero-Padding Strategies - Computing Transform Length For 1-D applications with very long vectors, the time required to compute the transform size could be significant.
MATLAB FFT Zero-Padding Strategies - Small Prime Factors "The standard FFTW distribution works most efficiently for arrays whose size can be factored into small primes (2, 3, 5, and 7), and otherwise it uses a slower general\-purpose routine."
Horn Thinking About the Word "Amateur" You can't avoid English words that have ambiguous meaning; they are everywhere.
MATLAB FFT Zero-Padding Strategies - Introduction FFT-based convolution can be performed faster by using a different zero-padding strategy than what is commonly used.
MATLAB Initialize a MATLAB Toolbox As I learned during my MathWorks career, a set of recommended practices is much more likely to take hold if it can be automated.
