傅立叶变换的matlab实现和傅立叶反变换的matlab实现，入口参数是：t和f，出口参数是f和t(Matlab Fourier Transform and Fourier Transform realize the matlab realize, the entrance parameters are: t and f, the export parameters are f and t)

sinc插值，可以理解为所有输入样本的加权叠加(sinc interpolation, can be understood as a weighted superposition of all input samples)

四阵元理想情况下情况下，来波方向为30度时，波束赋形( Smart Antenna beam-forming)

可以进行离散信号与连续信号的卷积演示的界面，包括各种信号的演算，可展示结果。(Can be discrete convolution signal with a continuous signal interface presentation, including the calculation of various signals, display the results.)

改进的matlab导航算法文件，实现更搞笑的导航解算(improved matlab navigation algorithm, more effecient navigation computation is implemented)

光学单缝衍射是光学中经常用到的实验，该实验能够很好地模拟光学实验，希望各位好好下载，不懂跟我联系(Single slit diffraction )

说明：  哈尔小波转换 一维信号与二维图像的三级分解 信号去噪与重构 morlet小波连续小波变换(Haar wavelet Three level decomposition of one dimensional signal and two dimensional image Signal denoising and reconstruction morlet wavelet continuous wavelet transform)

求解出在最小均方误差滤波器单位冲激函数h(n)。求解过程需要通过利用循环嵌套的编程思想，比较在逐次增加滤波器阶数的过程中得到的最小均方误差与最初设定的最小均方误差的阈值，当达到要求时，可以进一步确定滤波器的阶数。(how to use this function: [hx,hy]=wiener_ch2(w,N) )
