For today's blog entry I'd like to introduce Stephen Carter. Stephen is an engineer on the MATLAB Test Frameworks team and has been involved in many exciting new features over the past few releases (and he continues working on more to come!). Stephen was excited to write a post or... read more >>

Today it is my pleasure to introduce my MathWorks colleague Anoush Najarian. Anoush is an engineering manager on the MATLAB performance team and she has been instrumental in many great projects such as the performance testing framework we have been blogging about as well as the significant performance improvements with... read more >>

OK, I had way too much fun writing that last blog post exploring algorithmic scaling. I want to explore this a bit more with a some "real" code, and what is more real than a function to calculate the lovely fibonacci number, the darling of interview questions, algorithms classes, and... read more >>

To scale or not to scale. That is the question. When talking about algorithmic complexity, the answer to said question is usually an important one. No matter what the constant factors are that affect your algorithm's speed, poor scaling performance severely limits the scope of the problems you can solve. How do you measure your code's runtime complexity? If you don't have a good method for this (or even if you do!) then once again the performance testing framework is on your side. I was amazed when I learned of this one weird trick to measure the complexity of my algorithms.... read more >>

We saw last time how we can use the performance testing framework to easily see the runtime differences between multiple competing algorithms. This can be done without needing to learn about the philosophies and guiding principles of the framework, indeed you don't even need to know that you are using a performance test framework or that the script you are writing is actually even considered a "test".... read more >>

Have you ever wondered how to compare the relative speed of two snippets of MATLAB code? Who am I kidding? Of course, we all have. I am just as sure that you already have a solution for this. I know this because all around the internet I have seen people... read more >>

There are so many cool features in 2016a. Live Scripts are huge. The App Designer is a game changer. The language and environment keeps moving ahead with many exciting features.... read more >>

Ajay Puvvala is my friend and colleague at the MathWorks. He also led the development of the TestTags feature we spoke about last post.... read more >>

I have found that with any reasonably sized software project, sooner or later organization becomes important. As additional features and capabilities are introduced into a toolbox it becomes important to quickly and easily get your hands on the right piece of code for the task at hand. When we are... read more >>

I once faced a question from a friend who was perusing MATLAB documentation while implementing a test suite for some production software and found an example test which used the addTeardown method of the TestCase object. This person found themselves wondering why they might want to use it to... read more >>
