On Leap Day, 2008, I posted about how to time code in MATLAB, and I gave a link to a timing utility function called timeit that I submitted to the MATLAB Central File Exchange. If you use... 続きを読む >>

The MathWorks is running a broad MATLAB user survey, asking general questions about product usage and workflows. I hope some of my blog readers will consider taking a few minutes to respond... 続きを読む >>

The MathWorks updates its product line twice per year on a regular schedule. Early last month we shipped our second release of the year, R2008b. My fellow bloggers have already been... 続きを読む >>

Are you a scientist user of MATLAB? My friend Greg Wilson of the University of Toronto just sent me notice of a survey you might be interested in: Computers are as important to modern... 続きを読む >>

We looked at the decomposition of different structuring element shapes in my previous post on dilation algorithms. Today let's time some code to how decomposition makes a real difference in... 続きを読む >>

Did you know that MathWorks publishes information about product bugs on its web site? And that you can be automatically notified with updates regarding specific bugs, or regarding specific... 続きを読む >>

In my previous post on dilation algorithms I discussed structuring element decomposition. We looked at the decomposition of structuring elements with rectangular domains. Today I want to... 続きを読む >>

Do you read any of the other MATLAB Central blogs? There's a lot of good information on them. For several years, the "Pick of the Week" blog has regularly highlighted the best contributions... 続きを読む >>

This is the second post in my series on algorithm concepts behind the implementation of dilation and erosion in the Image Processing Toolbox. Today I want to talk about structuring... 続きを読む >>

Today's post is brought to you directly from the software developer half of my brain. MATLAB 6 was the first version to use the FFTW library for fast Fourier transform computations, and I... 続きを読む >>
