Beatty-(12)
Reconstruction of magnetic resonance images from
data not falling on a Cartesian grid is a Fourier inversion problem
typically solved using convolution interpolation, also known as
gridding. Gridding is simple and robust and has parameters,
the grid oversampling ratio and the kernel width, that can be
used to trade accuracy for computational memory and time
reductions. We have found that significant reductions in computation
memory and time can be obtained while maintaining high
accuracy by using a minimal oversampling ratio, from 1.125 to
1.375, instead of the typically employed grid oversampling ratio
of two. When using a minimal oversampling ratio, appropriate
design of the convolution kernel is important for maintaining high
accuracy

FitzHughNagumo
Unscented Kalman Filter (UKF) exemplified on FitzHugh-Nagumo neuron dynamics.
Voltage observed, currents and inputs estimated.
FitzHughNagumo.m is the main program which calls the other programs.
If you use these programs for your publications etc., please refer to
