Description: This function computes Euclidean distance transform for 3D binary image with non-trivial aspect ratio (i.e. anisotropic pixels). The algorithm uses fast optimized line-scans and is actually faster than MATLAB s BWDIST implementation of search on optimized kd-tree for many cases. It also uses cell-array representation for internal data, and thus is less demanding to physical memory.

Description: This a collection of MATLAB functions for extended Kalman filtering, unscented Kalman filtering, particle filtering, and miscellaneous other things. These utilities are designed for reuse and I have found them very useful in many projects. The code has been vectorised for speed and is stable and fast.

Description: 本人修改过的elm的matlab算法，该算法比原来的elm的算法在超过3个神经元后的计算速度能明显加快！原理是运用函数产生列矩阵！！
ELM 是一种快速的神经网络算法，本人已经比较过，比很多流行的算法（BP,SVM）都快,而且效果很好，运行环境是matlab，可以测试所有的benchmark的数据-I modified elm of matlab algorithm elm than the original algorithm in more than three neurons after the computing speed can significantly speed up! The principle is to use functions to generate the matrix out! ! ELM is a fast neural network algorithm, I have a comparison, than many popular algorithms (BP, SVM) faster, and the effect of good operating environment is matlab, you can test all of the benchmark data

Description: 最近和一位研友交流时谈到Matlab时频分析，了解到Matlab并不提供直接的绘制时间-频率分布图的命令，而是以时间-尺度图代之。不过很多时候我们要用到时间-频率图来分析信号，这两天集中搜集了相关的资料，其中在 MathWorks.com 的 Fileexchange 中心找到一个不错的Matlab时频分析工具，使用 Matlab GUI 界面开发，内核用C编写，感觉使用方便，分析和作图速度快，而且有多种图形表达方式选择。-Friends of the recent research and a reference to communicate Matlab time-frequency analysis, that Matlab does not provide a direct rendering of time- frequency distribution of command, but in time- Scalogram instead. But often we spend time- frequency diagram to analyze the signal, these two days focus on relevant information collected, of which the Fileexchange in MathWorks.com Center Matlab to find a good time-frequency analysis tool, the use of Matlab GUI interface development, which the preparation of nuclear use C, I feel easy to use, fast analysis and mapping, and expression has a variety of graphics options.

Description: The function implement the 1D sequency(Walsh) ordered fast Walsh-Hadamard transform which can be used in signal processing, pattern recongnition and Genetic alogorithms.
This algorithm uses a Cooley-Tukey type signal flow graph and is implemented in N log2 N additions and subtractions. Data sequence length must be an integer power of 2.
The inverse transform is the same as the forward transform except for the multiplication factor N. This can be easily achieved by deleting the last line i.e. x=inv(N)*x
Example:
x=[1 2 1 1]
W=FWHT(x) -The function implement the 1D sequency(Walsh) ordered fast Walsh-Hadamard transform which can be used in signal processing, pattern recongnition and Genetic alogorithms.

Description: 二维傅里叶变换,对图像进行二维傅里叶变换处理-Two-Dimensional Fast Fourier Transform
The purpose of this project is to develop a 2-D FFT program "package" that will be used
in several other projects that follow. Your implementation must have the capabilities to:
(a) Multiply the input image by (-1)x+y to center the transform for filtering.
(b) Multiply the resulting (complex) array by a real function (in the sense that the
the real coefficients multiply both the real and imaginary parts of the transforms).
Recall that multiplication of two images is done on pairs of corresponding elements.
(c) Compute the inverse Fourier transform.
(d) Multiply the result by (-1)x+y and take the real part.
(e) Compute the spectrum.
