matlab 环境下的 二维小波变换（正和逆变换），用二维卷积实现的，其中有个子函数用于产生小波系数的（小波分解和小波重构的系数都有）！你自己也可以往里面加系数-Matlab environment 2D wavelet transform (and inverse transform), with the realization of two-dimensional convolution. these subsystems function used to generate the wave

用MATLAB实现递推数列的卷积和FFT算法-Using MATLAB implementation of the FFT algorithm for recursive sequence

FFT和IFFT的MATLAB实现代码 用时间抽取的基2快速傅里叶变换实现序列卷积 对利用自编函数对信号进行DFT变换 对利用自编函数对信号进行DFT反变换-FFT IFFT dft

已知两个信号序列： 用conv函数求两个序列的卷积和，并绘制三个序列的波形。(Two signal sequences are known: The convolution sum of two sequences is obtained by using the conv function, and the waveform of the three sequences is drawn.)
