matlab经典算法的程序 最速下降梯度法matlab程序(classical algorithm matlab procedure steepest descent gradient method matlab program)

有关信号的循环谱计算，内容详细，含注释！！！(Signal cyclic spectrum calculation, detailed content, including the Notes! ! !)

Contourlet变换思想，选用拉普拉斯塔式滤波器结构对图像多分辨率分解来捕捉奇异点。(Contourlet transform thinking, the choice of Laplace tower filter structure for multi-resolution images to capture the singularity exploded.)

说明：  频分复用(FDM，Frequency Division Multiplexing)的matlab实现，仿真时录入三路声音信号进行处理，将用于传输信道的总带宽划分成三个子频带，经过复用以后再将录入的声音信号恢复出来。(FDM (frequency division multiplexing) is realized by MATLAB. In the simulation, three sound signals are input for processing. The total bandwidth used for transmission channel is divided into three sub bands. After multiplexing, the input sound signals are recovered.)
