Summary:
A team of engineers has proven that their analog computing device, called a
memristor, can complete complex, scientific
computing tasks while bypassing the limitations of digital computing.

I have an issue with calling a memristor a 'computing device'. If
If you can do matrix computations with it why not?
quote from that llnk:
"When organized into a crossbar array,
such a memristive circuit does analog computing by using physical laws
in a massively parallel fashion, substantially accelerating matrix operation,
the most frequently used but very power-hungry computation in neural networks
"

Well you could store analog info in CMOS too, even in capacitors.
Inductors? not so sure, not so easy for a long time?
Does core memory qualify as inductors?
Memory cores have a very wide hysteresis. You need a fair bit of
current to magnetize them, and when they do, they go straight into
saturation and stay there when the current is removed. You have to
reverse the current to magnetize them the other way and again will
flip the whole way.

That's why they were useful as memory. As inductors, not so much.
