what does he do these days?
The determination they came to was that MATLAB is an array lang but not an iversonian array lang.
symbolic algebra package and a computer language are not the same thing :) not even remotely.
to hell with peanuts: i'm pretty sure someone must even built cpython interpreter to wasm target, why not. there is no limit of what can be achieved by a group of motivated people with zero sense of direction.
k, however, makes quite a bit of sense on the web - also on your phone. and time to prompt is going to be MUCH faster than python and octave. and i mean their native builds :)
backslash is reference card, cmd+[] some examples
coming from javascript world this is super interesting, i will try and document some of the stuff i learn on that site is well.
You are working in a REPL, starting with small expressions to verify they are roughly doing what you want and then composing them to build up until you can plug it all together and now have a formula you can plug into the calculator to plug and chug all the rest of your data.
So in that sense yeah it does kind of replicate the magic of the first time you got a complex equation or BASIC program to run on your TI back in your school days.
if you don't mind sharing: how did your own first working program felt like, and what was it written in?
by the way, did it work, or did it work correctly? it's a small but important distinction.
