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 fas ...

Solving Engineering Problems Using MATLAB C++ Math Library Introduction
In the previous article, we studied how can use MATLAB C API to solve engineering problems. In this article I will show you how can use MATLAB C++ math library. The MATLAB&reg C++ Math Library serves two separate constituencies: ...

As all of you know, MATLAB is a powerful engineering language. Because of some limitation, some tasks take very long time to proceed. Also MATLAB is an interpreter not a compiler. For this reason, executing a MATLAB program (m file) is time consuming. For solving this problem, Mathworks provides us ...

AutoBoot is a generic boot loader that automatically locates, loads, and
executes object files from multiple types of media. AutoBoot provides a simple,
fast, and functional means of loading an OS image while maintaining a small
Flash memory footprint. This binary release contains a stand-alone vers ...

When working with mathematical simulations or engineering problems, it is not unusual to handle curves that contains thousands of points. Usually, displaying all the points is not useful, a number of them will be rendered on the same pixel since the screen precision is finite. Hence, you use a lot o ...

This string-include defines all string functions as inline functions. Use gcc. It also assumes ds=es=data space, this should be normal. Most of the string-functions are rather heavily hand-optimized,
see especially strtok,strstr,str[c]spn. They should work, but are not
very easy to understand. Every ...

Back in 2002, the 6502 disappeared out of all catalogues.
Wanted to know, if it s possible to build a binary compatible CPU with the things I had in the drawer:
74LS parts, 27C512 EPROMs and a fast static RAM from an old 80386 motherboard.
Now here the results.
Note, that the Bus timing is diff ...

Nagios is a powerful host and service monitoring program designed to run on most *NIX systems. It is written in C and designed to be fast and flexible. It has the ability to contact administrators via email, pager, or other user-defined methods.
数学计算 DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具
DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具，直接计算DFT的计算量与变换区间长度N的平方成正比。当N较大时，因计算量太大，直接用DFT算法进行谱分析和信号的实时处理是不切实际的。快速傅立叶变换(Fast Fourier Transformation，简称FFT)使DFT运算效率提高1～2个数 ...

Squaring circuits are an important building block for impulse-radio UWB non-coherent receivers. This work proposes a squarer, based on the quadratic law of saturated transistors. Such a circuit has already been proposed for lower frequency applications, therefore this work focuses on the extension t ...
