Visual Math 4D

I installed this app mainly for plotting complex functions. I wanted to have a better understanding of wave functions in quantum mechanics. However, there is no way to plot complex functions despite the app descriptions!

I used this app's export function for papers and lectures several years ago. I recently came back to it, to plot some practice error surfaces for adaptive filters. But now I can't find the "Save" button/menu to save the whole set of equations, not just the exporting plots. The export menu doesn't seem to have a Save item. I checked with the dev's website but couldn't find anything. Any help appreciated.

Wonderfully good graphs. And graphics!

Clearly many nice things about the calculator, but I couldn’t get it to plot a complex function using standard notation. Tried multiple plotting types, multiple ways of input. It’s either a limitation of the system or the documentation— either way there are too many competitors for me to continue spending effort trying to decode the limitations of the app. Pity — as this would be great for plotting wave equations. (It does work with sin/cos expressions — but I’d rather type my equations in b

Really great App. Awesome work here. I have a iPhone 4, not even 4s (slow processor) and it works Great! Highly recommend! 👍👍👍
