About PicPackager Digital cameras take large pictures that are difficult to e-mail and store. PicPackager will automatically shrink and zip an unlimited number of images with as few as 4 clicks. Twelve pictures on a digital camera can take up more than twenty megabytes before PicPackager resizes...

This script is a groupby function for arrays. Given a list of arrays and a `key` function, it will group each array based on the value of `key(args[0])`. The returned arrays will be two dimensional. The size of the first dimension is equal to the number of groups, and the size of the second...

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself....

Split the signal S(SPACE,TIME) into its downward/upward space propagating and stationnary components via a 2D Fourier decomposition. S is a (SPACE,TIME) matrix. We eventually proceed to a space and/or time filtering. DT,DX are temporal and space step. PERIOD=[Tmin Tmax] and WAVELENGTH=[Xmin Xmax]...
