This function calculates physical bounds on Q and D/Q for linearly polarized antennas composed by non-magnetic materials and circumscribed by various geometries as described in:Gustafsson, Sohl, and KristenssonIllustrations of new physical bounds on linearly polarized antennas,IEEE Trans....

Functions for Rice/Rician PDF: summary statistics (mean and variance), generating random samples, and simple moment-matching to fit the distribution to data.Similar to e.g. normpdf, normstat, normrnd and normfit from the MATLAB statistics toolbox, but for the Rice distribution, which is useful in...

Conceived for functional Magnetic Resonance Imaging, create_mosaic may also be useful for DWI or other applications which create image time-series Most fMRI programs use 4D matrices (x,y,z,t) in NIfTI format. It can be useful to reduce the number of dimension from 4 to 3 by tiling all slices (z)...
