When did you first get uncovered to MATLAB and Simulink?
I first discovered MATLAB through the second semester of my freshman 12 months of faculty in a common engineering course. This got here proper after studying 3D CAD modeling and, admittedly, it was a jarring swap. MATLAB was launched as ‘one thing we would have liked to know.’ Nonetheless, my engineering colleagues and I had been centered on design and manufacturing and had been confused as to why we would have liked to start out programming. We used the language for the semester after which didn’t contact MATLAB once more in our engineering curriculum till our junior 12 months in Numerical Strategies.

So, you weren’t hooked straight away?
No. I used to be not a fan of MATLAB to start out. I had no motivation as a result of I didn’t perceive why I wanted to be taught MATLAB in my freshman 12 months.
What modified your thoughts?
The primary time I considered MATLAB as one thing that might assist me with coursework was in my Linear Algebra class. We had been fixing matrix capabilities (e.g. multiplication, determinants, Gaussian elimination) by hand and I started utilizing MATLAB to examine my solutions. It actually helped me earn my ‘A’ in that class!
I appreciated the language solely after realizing the advantages. In Numerical Strategies, we started working with issues that had been not attainable to unravel analytically. Seeing how MATLAB might present approximate, numerical options to advanced issues was empowering and thrilling. It was then that I truly discovered MATLAB and actively sought to enhance my coding expertise.
What else did you employ MATLAB for at school?
My MATLAB utilization grew exponentially in ocean engineering graduate college. Lessons akin to Acoustics, Oceanographic Knowledge Evaluation, Random Processes, and Probabilistic Robotics all relied on MATLAB to churn via information and generate outputs. Moreover, I used MATLAB for my Masters Thesis analysis venture, seafloor mapping with machine studying, to check out code ideas earlier than writing compilable C++ packages.
MATLAB’s aggressive benefit over different languages grew to become clear when my pal and I needed to develop a robotic particle filter algorithm to trace a free-falling ocean automobile because it drifted 8,000m to the seafloor. We ran a for loop in MATLAB to repeatedly replace the state estimate of the automobile, and ChatGPT supplied methods to hurry up the algorithm (parfor loops, decreasing information switch between capabilities, and pre-allocating area for big matrices). Due to MATLAB’s ease of use, we accomplished this venture in 4 weeks, wrote a paper, and introduced our work at a convention a number of months later!

You began a YouTube channel. Why did you determine to take action?
I needed to supply college students and younger professionals a possibility to be taught the MATLAB language via a greater lens than after I discovered it. I imagine engineering brains are wired otherwise than laptop scientists’ brains, and thus the tutorial approaches to show engineers how you can code should be adjusted. As engineers, we’d like sensible examples of how MATLAB can be utilized to suit a curve to information, carry out numerical integration, or calculate a gradient, whereas additionally understanding foundational ideas like information varieties and information constructions. I regularly attempt to coalesce these ideas collectively into my YouTube movies and want to present a snug platform for brand new learners.
You’ve sturdy opinions about how MATLAB is taught in engineering faculties.
I believe there must be structural modifications in the best way universities embrace programming all through the curriculum. We have to see constant utilization throughout programs, throughout each educational semester. In Materials Choice, for instance, homework issues ought to ask for the stress seen for every widespread materials at quite a lot of thicknesses (somewhat than stress skilled by a 48” cantilever beam fabricated from metal). We are able to transfer from a single computation finished by hand (the ladder) to utilizing a number of matrix calculations that assist us perceive materials behaviors broadly (the previous). If this method may be taken for every class, then engineers will likely be outfitted with a mindset that inherently incorporates programming, somewhat than utilizing MATLAB purely as an afterthought.
What do you do for work now? Have been MATLAB expertise helpful to get to the place you now have?
At present, I work as a robotics researcher at a coastal analysis laboratory. MATLAB was actually a requirement, along with Python, as they’re ‘widespread languages’ spoken throughout researchers from totally different fields. Nonetheless, extra essential than understanding the language itself was demonstrating my potential to use a programming language to unravel a posh drawback. That’s what it actually means to ‘know a language’ and that’s what employers wish to see.
Do you employ MATLAB at your job? In that case, are you able to share one thing fascinating about your use of MATLAB at your job?
Sure, I take advantage of MATLAB amidst quite a lot of programming languages. Day by day, I’ve to ask myself what software to make use of to unravel a given job. Some days are spent in Python operating scripts on a RaspberryPi, others are spent taking a look at sensor information .mat recordsdata in MATLAB, and others are spent studying new frameworks like Docker to spin up Linux environments so tasks can run easily. I’ve began seeing the macro-perspective of embracing every language for what it’s finest at. And in relation to getting an idea working, fast n’ soiled, I all the time flip to MATLAB first!
