This function implements vectorized FFTs on a GPU. The answer is the same as the fft and ifft matlab functions.
You need to install the GPUFFTW2.0 library of Naga K. Govindaraju http://gamma.cs.unc.edu/GPUFFTW/ . On Naga's wed site, you can see the system requirements. It works on linux and windows.
This function support real and complex FFTs. I don't recommend this program for small fft. It really worth it...
Calculates the length of daylight for any day of the year and latitude.
This uses Herbert Glarner's formulae which do not take into account refraction, twilight, size of the sun, etc http://herbert.gandraxa.com/herbert/lod.asp.
GAUSSian REALIZation of a random variable with standard deviation sigma and correlation length lambda
This plugin is small, but very functional plugin-manager which contains necessary and useful patchs. No more requirement to download many plugins, you can use just one, and set up everything you need. At present it unites in itself the...
Transmission line length formula for coaxial cable to an antenna(the velocity factor for coax is approximately 0.66)frequency is in Mhz,length is in feet.
Computes the distance 2-point correlation function of a finite 2D lattice. The functions is:
[ coorfun r] = twopointcorr(x,y,width,height,dr)
Where x is the list of x coordinates of lattice points. y is the list of y...
The function circumcircle takes input as the coordinates of the three vertices of a triangle and compute the circum center and circum radius by using the formula in terms of the length of sides and area of triangle and plot the circumcircle.
Description:
This module adds an extra tab to each webform node, allowing you to specify validation rules for your webform components. You can create one or more of the predefined validation rules, and select which webform...
Find sequences of repeated (adjacent/consecutive) numeric values. Finds sequences of NaNs and Infs too.
SYNTAXES: (1) FINDSEQ(A) Find sequences of repeated numeric values in A along the first non-singleton dimension. A shuld be a...
The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is...
This program is used to calculate the Relative Strength Index (RSI) technical indicator for a user-provided vector giving stock prices. The user may also specify the number of samples to use for each period. The default period is 14 samples.
Best-Of Comments allows anyone with the ability to edit comments to mark a comment as dÂ¬DSdufeatureddÂ¬DSdu and then featured comments will be randomly selected and displayed anywhere you choose to place the php call to best_of_comments().
This program to perform convolution has been written keeping the ordinary polynomial multiplication in mind and in my opinion is the most easily understood program among the ones I have seen on the web or written by other fellow workers although...
DICOM is a rather complicated format. The DICOMINFO and DICOMREAD functions provide easy access to the data in DICOM-formatted files, but it can be difficult to know why and where the DICOM parser fails for improperly formatted files.
Attachment expiration module provides a method to remove attachments while leaving the nodes housing the attachments in place. This module is helpful in situations where space is a concern, or the actual content is archived elsewhere.
a gui which allow measuring an areas size and a paths length on an image (map).
You can calibrate the image scale.
You place points using left mouse button and remove points & areas with right mouse button.
You...
This include a MEX-DLL file which is an implementation of R L Siddon's refined method by Jacob for the calculation of ray path integral in PET/CT system image reconstruction. This is based on Line Intersection Length model to calculate probability...
Spectrum scope makes it easy to compute and display the fft of a live signal. You feed it your time series data, and it does the rest. It works very nicely with the Timer objects introduced in R13, and with Analoginput objects (from the Data...
The PRBS are based on 3 to 9 bits memory delays and put out 2^3 -1 to 2^9 -1 binary sequence length. Usage: these generators can be used in process identification as noise source on command signal
This mdf-import function is a modification of Stuarts MDF import tool. A resampling functionality to a unique time signal has been added to allow easy access to all signals and simplify plotting and other analysis with a comon time vector. The... |
