# Importance of Implicit Expansion For Performance6

Sometimes people state that they like using MATLAB because it's easy to express their mathematical thoughts. Sometimes there's a follow-on that they then switch to another language for performance. While early in the history of MATLAB, that was sometimes beneficial, it is not so obvious these days. Let's take the example of implicit expansion (also here).... 続きを読む >>

# Time Zones and Time Zone Offsets

Peter Perkins, in development, wrote this as an explanation for what the development team and documentation needed to understand to make sure time zones were implemented and explained correctly. I stole it (with his permission) to share with you.... 続きを読む >>

Today I’d like to introduce a guest blogger, David Garrison, who is a MATLAB Product Manager here at MathWorks. Dave will talk about the new feature introduced in R2019b called Live Editor Tasks which allow you to complete steps in your workflow interactively from within the Live Editor.... 続きを読む >>

# Which Way to Compute: cellfun or for-loop?9

Over a long number of years, people have asked whether it's better to use cellfun or a for-loop to perform certain computations. As with so many things in life, the correct answer here is "it depends". Let me give you a bit more insight so you can make good choices.... 続きを読む >>

# Compose Yourself!9

Even if we crunch numbers a lot, there are plenty of times, for example, when reporting, that we need to mix numbers into text. For a very long time, we've been able to create a character vector, and more recently, a string, with functions like sprintf. Look here for more information on character arrays and strings.... 続きを読む >>

# Estimating pi Using Buffon’s Method6

I recently attended the ICIAM meeting in Valencia, Spain which meant I got to hang out with my pals Carlos Sanchis and Lucas Garcia :-)! Carlos showed me a problem he was working with Professor Fernando Giménez from UPV regarding an app for estimating $\pi$ using Buffon's method. Here's the problem statement from Wikipedia:... 続きを読む >>

# Mathematical Word Problems – Construction Tool5

Do your kids have to practice solving mathematical word problems? Maybe they need to practice more during school breaks? I've written a function that can turn you in to a machine for torturing your kids with some.... 続きを読む >>

# Internet of Things – How to Get Started1

I'm sure you've heard of IoT, Internet of Things. And people talk about connected devices, and getting the data from them to use in applications. I want to show you a very simple example to spark some ideas in each of you.... 続きを読む >>

# dimsum in MATLAB12

As Steve noted in a recent post, several of the functions that operate along specific dimensions have been updated to add some new functionality, for example the function sum. (I also think he missed a great opportunity for a cool blog post title, which is only partly why I am writing about it now :^) ). Please read his post!... 続きを読む >>
