However, developing software of this quality is by no means inexpensive, and I wouldn’t be surprised to learn that the cost of a standard MATLAB license doesn’t fit within the budgetary constraints of numerous entrepreneurs, consultants, startups, and small engineering firms. I’ve done quite a bit of work with MATLAB over the years, and it is undoubtedly a powerful tool that can simplify and accelerate a wide variety of engineering tasks.
