Have you ever wished you could start using the Julia programming language to develop custom models? Does the idea of replacing outdated MATLAB^® code and models seem overwhelming?

Or maybe you don't plan to replace all MATLAB code, but wouldn't it be exciting to integrate Julia code into existing workflows?

Also, technicalities aside, how do you convince your colleagues to make the leap into the Julia ecosystem?

I'm excited to share an announcement! At this year's JuliaCon, I will be speaking about a small but significant step you can take to start adding Julia to your MATLAB codebase.

Great news! You can transition to Julia smoothly without completely abandoning MATLAB. There's a straightforward method to embrace the best of both worlds, so you won't need to rewrite your legacy models from scratch.

I'll give my full talk in July, but if you don't want to wait, keep reading for a sneak peek!

Background

The GLCS.io team has been developing Julia-based solutions since 2015. Over the past 4 years, we've had the pleasure of redesigning and enhancing Julia models for our clients in the finance, science, and engineering sectors. Its incredible speed and versatility have transformed how we tackle complex computations together. However, we also fully acknowledge the reality: MATLAB continues to hold a significant place in countless companies and research labs worldwide.

For decades, MATLAB has been the benchmark for data analysis, modeling, and simulation across scientific and engineering fields. There are likely hundreds of thousands of MATLAB licenses in use, with millions of users supporting an unimaginable number of models and codebases.

Even for a single company, fully transitioning to Julia often feels insurmountable. The vast amount of existing MATLAB code presents a significant challenge for any team considering adopting Julia.

Yet, unlocking Julia's power is vital for companies aiming to excel in today's competitive landscape. The question isn't if companies should adopt Julia---it's how to do it.

Companies should blend Julia with their MATLAB environments, ensuring minimal disruption and optimal resource use. This strategic integration delivers meaningful gains in accuracy, performance, and scalability to transform operations and drive success.

JuliaCon Preview

At JuliaCon, I'm excited to share how you can seamlessly integrate Julia into existing MATLAB workflows---a process that has delivered up to 100x performance improvements while enhancing code quality and functionality. Through a real-world model, I'll highlight design patterns, benchmark comparisons, and valuable business case insights to demonstrate the transformative potential of integrating Julia.

(Spoiler alert: the performance improvement is more than 100x for the example I will show at JuliaCon.)
