Python® ベースの AI モデルを MATLAB および Simulink のワークフロー内で活用しやくするよう機能を拡張してきました。いまでは PyTorch® や TensorFlow™ モデル、または任意の Python コードを MATLAB から直接呼び出すことができます。例えば、Python ベースのモデルを比較して、その精度とパフォーマンスを評価し、MATLAB…

Today, we’re sharing some predictions on what the startup ecosystem might look like in 2025. In no particular order, here are some of the key themes we anticipate:


Corporate Engagement in Startups – We’ve seen a rise in large corporations interested…

Last year I discussed the collaboration between the open source optimization library, HiGHS and MathWorks. This included some exciting new integration of the HiGHS library with MATLAB which, among other things, is speeding up MATLAB's linear and mixed-integer…

As hospitals integrate more advanced patient monitoring systems, the ability to process, analyze, and act on real-time medical data has become critical. Traditional monitoring systems generate large amounts of sensor data, but manually interpreting this data…

皆さんこんにちは、トレーニングチームの遠藤です。

昨年末ゲーミング PC を買ったのですが、今までスペックギリギリで動いていたゲームがサクサク動くので、恥ずかしながら最近はゲーム三昧の自堕落な生活を送っています。最近のゲームはどれもグラフィックスがキレイなので、ゲームの世界に入り込んでいるような感覚になってしまいますよね……。

ということで、今回は「グラフィックス」繋がりで、MATLAB のグラフィックスの根幹を担っている「グラフィックス オブジェクト」についての技術記事になります！

Professor Kichun Jo's team from Hanyang University clinched victory at the 2023 Hyundai Motor Group Autonomous Driving Challenge. The competition is a real-vehicle-based autonomous driving competition where vehicles recognize roads and surrounding…

Give ThreadPool a tryIf you have some parallel MATLAB code and want to try something that may make it go faster then I suggest opening your Parallel pool as follows before running your code.parpool(

Two years ago, in March of 2023, an unlikely team of mathematical hobbyists announced the discovery of a remarkable 13-sided polygon that they nick-named the

I was recently discussing different ways to visualize the content of a Simulink model with colleagues. Working in technical support, I receive models from users every day and it's always useful to quickly get a feeling of
