QAM

该程序可实现图像四方向频谱划分，通过该程序，衣服图像四方向的信息会很好的展现出来。(This program can be divided into the spectrum of image four directions, through the program, four-direction image information clothes would show up well.)

说明：  将输入A律PCM编码器的正弦信号采样,进行PCM编码，求出编码器的输出码组序列。(legal importation A PCM encoder sinusoidal signal sampling, PCM coding, coding obtained the output code sequence.)

针对机械优化设计的matlab优化M文件集,非常有用(For optimization of mechanical optimization design matlab M-file set, very useful)

说明：  是随机过程中时间序列分析作业，基于Matlab编程实现模型判别，参数求取，模型预测等，另附有本人作业全文，供大家参考。(random process is time-series analysis of operations, based on the Matlab programming model checker, parameters strike, model projections, followed by my work, for your reference.)

IT gives the IFFT of the given signal

说明：  分形彩图的C或者matlab的源代，可执行的绘制彩色分型算法图形的C或者matlab的源代码，需要3段，也就是3张图。图片尽可能好看(The fractal color of C or matlab source code, executable drawing color genotyping algorithm graph C or matlab source code need 3 paragraphs 3 in Fig. Picture as possible look good)

说明：  条件语句是编程中最常用的结构，这里作一个演示结果的文件(conditional statement is the most commonly used programming structure here for a demonstration of the results of the document)
