normalization

this code is help you to draw Fourier Series . with this code you can change some variable and explain what change for education.

matlab segmentation of image to get blocks

倒立摆控制，可以调整参数自动仿真；图像显示清晰；直观效果；本人调试过，很好用！！(Inverted pendulum control, you can adjust the parameters of automatic simulation; image display is clear; intuitive effect; I debug, very good use!!)

matlab编程100例 1-32是：图形应用篇 33-66是：界面设计篇 67-84是：图形处理篇 85-100是：数值分析篇(matlab programming is 100 cases of 1-32: 33-66 chapter graphics applications is: interface design articles 67-84 is: graphics processing chapter 85-100 are: Numerical Analysis Section)

用matlab对ADC的输出进行fft分析，得到需要的SNDR、THD、SFDR、ENOB等信息。(With matlab fft of the output of ADC analysis, required SNDR, THD, SFDR, ENOB, and more.)

蚁群算法 邮轮港口进行云评价，评价指标为上文总结得出的港口条件、经济腹地、旅游情况和港口建设四项指标(matlab The director of the Nourishing the Planet Project said besides poverty and a lack of access to food, much food is simply lost. Worldwatch estimates 1.3 billion tons of food is wasted each year.)

matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如修改不严重，可提取隐藏信息，如果修改过多，则只能确定是否有修改，而不知道隐藏的信息是什么(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, such as modification is not serious, can extract hidden information, if too many modifications, you can only determine whether changes were needed, they do not know what information is hidden)

这个是用MATLAB中的SIMULINK做成的PCM编码器,使用MATLAB实现PCM编码和解码.(This is in SIMULINK with MATLAB made PCM encoder, the use of MATLAB realize PCM encoding and decoding.)

QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

It is a C code , also can be used in Matlab. It will help you in detection of people going through a infra red image.
