The Matlab code in this folder implements 1D-3D NUFFTs via fast Gaussian gridding. The convolution loops are written as C programs to be compiled as mex files from the Matlab command prompt. Further mathematical details about the code can be found in L. Greengard and J. Lee, "Accelerating the...

INVDISTGRID Simple, robust gridding using inverse-distance interpolation. [Xi,Yi,Zi] = invdistgrid[X,Y,Z,dx] Grids values in vector Z with coordinates X and Y into an array with spacing dx using inverse-distance weighting (default power =2). All data between grid points are used in weighting. If...

PITAN(NUM,DEN,W) plots the stability boundary locus L(KP,KI,W) in the (KP,KI)-plane for an LTI system with transfer function defined by its NUM, DEN coefficients and driven by a PI controller with transfer function, C(s)=kp+(ki/s). Frequency (W) gridding become important.The method works for open...
