Non-graphing calculator supporting complex matrices?

[Manolo Sobrino]

It has to do with memory and costs. You can't make now a scientific capable to do that, plus what they already do and sell it for 20$. Maybe you could after a fair amount of investment, but it makes no sense: these are retail prices and you see heavy discounts, imagine the margins.

Matrix operations are already limited by memory, complex makes it double (at least). You essentially want a graphing calculator that can't graph. There is no real market for that.

Even with Moore's law and cheap labour there's a limited number of miracles that you can perform for 20$
