Should we ban tic/toc? 27

Yesterday morning, I overheard my kids talking about a tic/toc ban which surprised me because they are not MATLAB users and not particularly well connected at MathWorks. How would they know about... read more >>

Faster Ordinary Differential Equations (ODEs) solvers and Sensitivity Analysis of Parameters: Introducing SUNDIALS support in MATLAB 4

Sensitivity analysis of CARRGO model

Late last year I introduced the new solution framework for solving Ordinary Differential Equations (ODEs) that made its debut in MATLAB R2023b. I demonstrated how it allowed users to do all kinds of... read more >>

How we made a better backslash in MATLAB R2024a 4

Few things say 'MATLAB' better than the backslash. So good, we put it on a T-shirt.As most people will be aware, the backslash operator solves a system of linear equations. That is, it finds the x... read more >>

Pi day: Using AI, GPUs and Quantum computing to compute pi

14th March is Pi Day, celebrated by geeks everywhere and a great excuse for technical computing bloggers to publish something tenuously related to pi and their favorite technology of choice. This is... read more >>

Life in the fast lane: Making MATLAB even faster on Apple Silicon with Apple Accelerate 11

Up to 3.7x faster Matrix-Matrix multiplication, 2x faster LU factorisation, 1.7x faster Cholesky decomposition and the potential for many more speed-ups across different areas of linear algebra in... read more >>

Partial sorting in MATLAB 5

I was recently working with a researcher who had to sort arrays of double precision numbers thousands of times. In his application, however, he didn't need the full sorted list. He only wanted the... read more >>

Direct submission to HPC clusters from MATLAB 2

More Compute, More Problems When it comes to High Performance Computing resources, I'm a lucky guy. I've got a fairly decent, 8 core desktop along with guest access to a reasonable number of... read more >>

From HPC consultancy to a faster fzero function in MATLAB R2023a 9

Sometime in 2021, I was doing some High Performance Computing (HPC) consultancy with a university in the south of England. This involved various things such as getting the code to scale across... read more >>

Working efficiently with data: Parquet files and the Needle in a Haystack problem 6

This is a guest post by Onomitra Ghosh who is the Product Manager for MATLAB Data Analysis and Big Data workflows. How big does data need to be before it can be called big? While there is no... read more >>

Function handles are faster in MATLAB R2023a 7

Roughly speaking, there are two ways we at MathWorks can speed up MATLAB. We can dive into individual functions to remove overheads, improve algorithms and so on or we can make performance... read more >>
