Linear algebra has been on my list of things to learn for a while. Finally taking the time to do so in the context of building this tool was a wonderful, multifaceted experience. I wanted to reflect on it. Needless to say, I’m neither a developer nor a mathematician. I’m sure I’ve overlooked a lot of stuff. Yet informally wandering through these fields is always a delight. The problems they address are captivating and their models for solving problems are mind-bendingly helpful.
