You are very right in that a product in this space has to meet a very high bar before it is useful compared to other things like Matlab. I have functionality to do things like differential equations, linear algebra, FFTs, but not really hard math things like symbolic integration. So, right now my targets are users that need something more powerful than excel but don't need the higher level features of matlab or python. To help acquire those people, I am writing a server side on AWS to let them solve large problems and simply pass the cost they incur on to them (for now). In this way, I can target small companies and let them solve some large problems without having to buy large servers. I am hoping that this side can pay for the development of the CAD system.
