K_means

This is a code of Pseudo-Arc Length Continuation Method , the method can be used for solving the nonlinear equations, the principle can re found in some text books. In the code,I prove the agreement of the code with other methods

这种方法一方面将像素的灰度值分散，可以分辨图象中比较细节的内容；另一方面，将图 象的灰度变化控制在一定范围之内，抑制了噪声的产生，较大程度上地保留了原始图象的亮度．(This approach on the one hand spread the pixel gray value, the more details you can identify the contents of the image the other hand, the image gray scale control in a certain range, suppress noise generation, a greater degree preserved on the original image brightness.)

很适合想学习matalab的人，无论初级者还是高级者，这都是一本好书(matalab study)

语音信号进行分析、处理和设计。用MATLAB做变声器的原理是通过改变输入声音频率，进而改变声音的音色、音调，使输出声音在感官上与原声音不同。变声器是借助对声音音色和音调的双重复合改变，实现输出声音的改变。通过自己发声，共振峰频率的改变是基于重采样实现的(Speech signal analysis, processing and design. MATLAB do voice-changer works by changing the input frequency of the sound, and then change the sound of the tone, pitch, so that the output audio with the original sound in different senses. Voice Changer is the use of sound timbre and tone of the dual composite changes, realize the output sound changes. Through their own sound, formant frequency change is implemented based on resampling)

阵列天线设计，提供方向图示意，计算阻抗等，很适用于初学者(array antenna design)
