Relative Frequency Histogram

Helps measuring the exact frequency of a signal within a range, by means of finding the maximum of the product of the signal with a sinusoid.Speacially useful when dealing with real-world data.As recently published on my blog: http://loluengo.blogspot.com

It is very fast and simple file to display histogram of a 3D imageimhist3(I,n) n is the number of bins in the histogramimhist3(X,map) X isindexed 3D image and map is colormap map

PCSA is a frequency domain analysis technique that can be used to transform PSDs (as those in a spectrogram) to the form of a two-dimensional histogram with frequency-magnitude bins. PCSA can be used to examine the spectral characteristics of a long period of data. It summarizes magnitudes and...

Easy Relative Date is a simple plugin to add relative date supports on wordpress powered websites, like 'Today', 'Yesterday', '2 Days Ago', '2 Weeks Ago', '2 'Seconds Ago', '2 Minutes Ago', '2 Hours Ago'. The main advantage of the plugin is that it doesn't override standard wordpress the_date()...

Frequency Response Correction is a Java application which works for Linux, Windows, Mac. Why Frequency Response Correction? The audio frequency reproduction in a normal listening room is not linear in its amplitude because of the room response which is defined by its resonances and reflections....

This script will create a column subset from a numeric spreadsheet, then take the row averages and create a histogram of those averages. You can specify the subset by column number or by marker (if the spreadsheet has a marker map). This is useful for LogR spreadsheets to investigate for possible...

The Blackbody Radiation: Frequency and Wavelength model simulates the blackbody radiation curves of Planck both as a function of frequency and as a function of wavelength to allow for comparison of the two functions. The Planck radiation law can be derived both as a function of frequency and as a...

CPU frequency governor selector is a simple script that allows you to choose the governor for your CPU's frequency. This is mostly intended as an alternative to the GNOME CPU frequency applet. It may not have as many options or be as convenient, but it doesn't rely on any aspects of GNOME and is...
