Provides useful functions for signal processing such as Fast Fourier Transform, windowing (apodization), variance/standard deviation and others.
Plots one-dimensional arrays as polylines (curves) in the browser, along with axes and legend text, with versatile view options.
Provides functions to detect (search, pick) peaks (maximum values) in one- or two-dimensional arrays, also suitable for noisy data.
Compresses large one- or two-dimensional arrays (vectors, matrices) to a reduced format retaining minimum and maximum values. Can also expand an array by interpolation.
This package contours the 3-dimensional surface represented by the values f(x,y) of a matrix. The detected contour lines are passed on to a user-provided renderer.
