A fourier filter for time-series signals. Version 1.5, May 4, 2007, is calibrated specifically for time-based signals. Does not require the Signal Processing Toolbox. By adjusting the parameters, you can create lowpass, highpass, bandpass, and bandreject (notch) filters with variable cut-off...

A collection of m-files aimed at learning and teaching about the principles of diffraction gratings. Some of these show a cross section of the geometry of a diffraction grating, a common illustration in textbooks of optics, spectroscopy, and analytical chemistry.Sliders on the figures allow...

A computational method for quantitative analysis by multiwavelength absorption spectroscopy, called the Tfit method, based on fitting a model of the instrumentally-broadened transmission spectrum to the observed transmission data. It has the advantages of wider dynamic range and greatly improved...

function ire(x, signal)Interactive resolution enhancement function for data in the arguments "x,signal". Displays sliders for real-time control of 2nd and 4th derivative weighting factors (factor and factor2) and smooth width. (Larger values of factor1 and factor2 will reduce the peak width but...
