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...
This m-file produces random numbers from the negative Binomial distribution using one of four methods and it tests which is faster.
y = RankOrderFilter(x, window, thd) runs a rank-order filtering of order N on x. y is the same size as x. If x is a matrix, RankOrderFilter operates along the columns of x.
Rank-order filter calculates the p'th percentile of the data on...
In image analysis, such as in the field of AFM topography, a standard problem is to fit polynomials of given ORDer to many columns of data, considered as different functions of the same independent variable. POLYFIC solves this problem in a...
This module will allow Drupal to replace textarea fields with the CKEditor - a visual HTML editor, sometimes called WYSIWYG editor. This HTML text editor brings many of the powerful WYSIWYG editing functions of known desktop editors like Word to...
Set difference of two sets of positive integers (much faster than built-in setdiff) which is great if you have to call it million times in a loop.
Simple program that makes it faster and easier to solve simultaneous equations using the solve command.
Find what you need quickly and efficiently. Much faster than browsing the HTML documentation.
Specify a vecter, a minimum peak separation, and a minimum peak height, and this function will find the peaks.. about 250 times faster than findpeaks would! try:
t=linspace(0,1,10001);
Phaeton is a multi user agent class written in PHP, capable of simultaneously downloading several remote pages over HTTP.
Use it instead of Snoopy, it is a lot faster if you need to get several pages.
Snazzy Archives is a visualization plugin for your WordPress site featuring an unique way to display all your posts. Your archive page will never be boring again!
Snazzy archives simply lets you express yourself and your blog. You can...
The conjugate gradient method aims to solve a system of linear equations, Ax=b, where A is symmetric, without calculation of the inverse of A. It only requires a very small amount of membory, hence is particularly suitable for large scale...
The Floyd-Warshall algorithm computes the all pairs shortest path matrix for a given adjacency matrix. The algorithm is O(n^3), and in most implementations you will see 3 nested for loops. This is very inefficient in Matlab, so in this version the...
scatterquad2(X,Y,Z) finds the volume under the surface defined by the points (X(i),Y(i),Z(i)) with linear interpolation on the Delaunay triangulation of (X,Y) and Z=0 outside the convex hull of (X,Y).
Example: load seamount
R = CRR(S) computes the radius of the mean-centered interval, circle, or sphere with 95% probability given S, which is either a vector of standard deviations or a covariance matrix from a multivariate normal distribution. If S is a real,...
Soda pop for your media. SuperSlider-Media-Pop adds numerous image enhancements to your admin panels. It adds image sizes to the Upload/Insert image screen, adding image sizes to be inserted and adding to the image link field options. Insert any...
This function implements a standard algorithm for computing factorials. It may not be the most efficient for very large arguments, but it is very transparent. The function accepts single numbers as inputs or arrays.
Note that for any...
Intersection of two sets of positive integers (works much faster than built-in intersect)
Automatic colorization of gray-scale images using color palette. A simple algorithm is employed. The speed of the algorithm and the quality of the result colored image depends on the correct selection of the color palette image. The...
This plugin caches every database query with given lifetime. It is much faster than other html caching plugins and uses less disk space for caching.
I think you've heard of WP-Cache or WP Super Cache, they are both top plugins for... |
