Planning to ... but just started !Has anybody implemented a Kalman filter on the Netduino that runs with good performance?

There's a good supplementary maths library here.I was just looking at porting some Kalman filters from C over to C# to run on the Netduino - however some of the System.Math functions are not available in .NETMF so it's going to take a bit of work. It might be worth implementing them in native code?

The effort is really appreciable, but it is not enough.There's a good supplementary maths library here.

Doing math in a managed way it results a very poor performance. I am fighting against a FFT and it takes almost 100ms to get the result (*VERY* simplified and with tons of hardness).

Another point over that particular library is to the square-root function I need to compute the modulus of a complex number. That algorithm is *really* slow.

Take a peek my article, if you interested in...

I'd expect to make simple calculations within microsecs, not millisecs.

Cheers
