Implement FFT and IFFT 16 point using Matlab Simulink.

eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital data signal from a receiver is repetitively sampled and applied to the vertical input, while the data rate is used to trigger the horizontal sweep. It is so called because, for several types of coding, the pattern looks like a series of eyes between a pair of rails. It is an experimental tool for the evaluation of the combined effects of channel noise and intersymbol interference on the performance of a baseband pulse-transmission system. It is the synchronised superposition of all possible realisations of the signal of interest viewed within a particular signalling interval.

一个使用数学方法生成波形声音文件的源代码，可以载入预置数学公式，保存8位和16位单声道声音文件，可以设置振幅、频率、持续、采样等参数，可以调整波形斜面，回声。 这个代码值得推荐！(The use of mathematical methods to generate a waveform sound files of source code, can load preset mathematical formula, save 8 and 16-bit mono sound files, you can set the amplitude, frequency, continuous, sampling and other parameters, you can adjust waveform slope, echo . It is recommended this code!)

说明：  基于MATLAB的工业瑕疵缺陷检测，采用工业板图像作为素材。利用灰度化，二值化，边缘提取，形态学运算等方法，检测并标出出瑕疵所在位置，计算出各个块面积。设计了一个UI界面，显示瑕疵个数和面积等参数。(Industrial defect detection based on MATLAB, using industrial plate image as material. Using gray, binarization, edge extraction, morphological operation and other methods, the location of defects is detected and marked, and the area of each block is calculated. A UI interface is designed to display parameters such as the number and area of defects.)
