Browser Guide
Use the RunMat sandbox, a browser-based IDE for writing and running MATLAB-style code with GPU acceleration, cloud storage, and file versioning.
The Worst Debugging Tool in MATLAB Is the One You Use Every Day
fprintf is a formatting function that got conscripted into debugging because MATLAB never shipped anything better. Here's what it's actually for, what it costs you as a debugger, and what to use instead.
MATLAB For Loops Are Slow, But Not for the Reason You Think
MATLAB for loops are slow because of interpreter overhead, not because iteration is inherently expensive. Here's what actually causes the slowdown, what vectorization costs you, and how a compiled runtime changes the tradeoff.
Version Control for Engineers Who Don't Use Git
Most engineers -- from MATLAB scripting to FPGA verification to test automation -- don't use version control because git wasn't built for them. RunMat gives engineers automatic versioning, snapshots, and audit trails without the cognitive overhead of learning a developer tool.
How to Use GPUs in MATLAB: Complete NVIDIA Setup & Optimization Guide
Step-by-step guide to GPU acceleration in MATLAB: system requirements, Parallel Computing Toolbox setup, gpuArray patterns, performance traps, and a cross-platform alternative.
MATLAB Alternatives 2026: Benchmarks, GPU, Browser & Compatibility Compared
A deep comparison of RunMat, Octave, Julia, and Python across 17 areas: execution speed, GPU acceleration, browser computing, airgap deployment, version control, and more. A 22-minute engineering guide.
What is MATLAB? The Language, The Runtime, and RunMat
A plain-English explainer of MATLAB's language model and how RunMat delivers a modern, high-performance open-source runtime for it.
