求水仙花数的源码，可以运行的，我是菜鸟，请大家都来指教下吧，谢谢了！(The source seeking a few daffodils, you can run, and I was rookie, let us all come under the Zhijiao bar, thank you!)

计算图像中的欧拉数，经典代码，采用matlab实现，可以熟悉欧拉数的求法，及相关MATLAB函数的用法，带图片可测试。(calculated image of Euler number, classic code using Matlab realized, could familiar with the Euler number for the law, MATLAB functions and related usage, with pictures can be tested.)

说明：  文主要目的是针对讯号频谱分析仪(Signal spectrum analyzer)做功能测试，以确定讯号频谱分析仪之各种运算功能正确，其中测试共 分为正弦与余弦波检查、反假象滤波器检查(Antialiasing Filter Check)、频率响应函数与相位角检查(FRF & Phase Check)、自身能量密度函 数检查(Power Spectrum Check)、动态范围检查(Dynamic Range Check)等五个项目的快速傅立叶转换检查(Fast Fourier Transform Check)，并 对五个项目之测试原理、测试步骤及测试结果加以说明，提供频谱分析仪功能测试之正确方法，亦可作为自制频谱信号处理单元及频谱分 析程式之验证。(The main purpose of the text is for the signal spectrum analyzer (Signal spectrum analyzer) to do functional testing, to determine the signal spectrum analyzer features a variety of computing the right, which is divided into sine and cosine test wave inspection, anti-false filter inspection (Antialiasing Filter Check), the frequency response function and phase angle of inspection (FRF &amp Phase Check), its energy density function check (Power Spectrum Check), dynamic range checking (Dynamic Range Check) and other five projects FFT check (Fast Fourier Transform Check ), and principles of the five test items, test steps and test results to show that the spectrum analyzer to provide the proper testing method may be used as self-spectrum signal processing unit and the spectral analysis of the verification.)

Intro to Matlab Statistics functions and applications

利用matlab实现功率谱估计中的间接法，不是通过函数调用实现的，是根据算法的思想，一步一步实现的，文件夹中还有实现自相关的算法(Using matlab to achieve the indirect method of power spectrum estimation, not by function calls, is based on the idea of ​ ​ the algorithm, step by step, the folder also auto-correlation algorithm)
