@SchighSchagh, Visual C++. gcc can't do it for compatibility reasons.

@Zaibis, It's 2015. C++ is C++14 unless otherwise stated.

comment Autonomous robot location detection indoors
Integration is simply multiplying each measurement by the time since the last and adding up. Of course, if you have angular acceleration, you have to convert it to linear, but that's also easy. There are probably ways of reducing error using the other sensors. This is just the simplest method.

comment Autonomous robot location detection indoors
Integrating acceleration gives velocity, and integrating velocity gives position. It won't be very accurate, though.

Fixed-length representation of an unbounded number of points is obviously impossible. Fixed-length representation of a fixed set is trivial — a binary mask. Something is missing here.
