matlab函数大全，matlab编程函数查询的工具文档(matlab study )

输入信号为方波信号+高斯白噪声，方波信号基 频为1kHz，幅值为1，高斯白噪声方差为0.2， 均值为0，采样频率为20kHz。试用最大熵估计 法估计此信号的AR模型及其功率谱，并分析结 果(The input signal is a square wave signal+ Gaussian white noise, square wave signal fundamental frequency 1kHz, amplitude is a Gaussian white noise variance is 0.2, the mean is 0, the sampling frequency is 20kHz. Try maximum entropy estimation method to estimate the AR model of this signal and its power spectrum, and analyze the results)

MATLAB软件中的另一种形式的仿真Simulink，分别仿真了BPSK,16QAM,2FSK,QPSK(MATLAB software in another form of simulation Simulink, were simulated BPSK, 16QAM, 2FSK, QPSK)

这个工具包包含的若干程序之一就是图像滤波与模糊处理的函数，用于图像处理。 包含文件有： .DS_Store, ._.DS_Store, apply_colormap.m, ._apply_colormap.m, barb.png, callback_ti_wavelets.m, ._callback_ti_wavelets.m, change_color_mode.m, ._change_color_mode.m, compile_mex.m, ._compile_mex.m, compute_avi_file.m, ._compute_avi_file.m, compute_dead_leaves_image.m, compute_directional_kernel.m, compute_gabor_filter.m, ._compute_gabor_filter.m, compute_periodic_poisson.m, ._compute_periodic_poisson.m, compute_random_patches.m, compute_ssim_index.m, 等等 (.DS_Store, ._.DS_Store, apply_colormap.m, ._apply_colormap.m, barb.png, callback_ti_wavelets.m, ._callback_ti_wavelets.m, change_color_mode.m, ._change_color_mode.m, compile_mex.m, ._compile_mex.m, compute_avi_file.m, ._compute_avi_file.m, compute_dead_leaves_image.m, compute_directional_kernel.m, compute_gabor_filter.m, ._compute_gabor_filter.m, compute_periodic_poisson.m, ._compute_periodic_poisson.m, compute_random_patches.m, compute_ssim_index.m, )

可以看到 变步长未必会需要更长的时间 因为它是一种自适应的方式 如果某阶段情况理想的话 就会用最大步长来做 那就会很快 (can see variable step may not need a longer period of time because it is an adaptive way if a certain phase of the the ideal would be the greatest step will be to do it quickly)

mimo系统通过波束到达角、角度扩展、天线之间的间隔和天线的个数，计算出发送端或接收端的相关矩阵(mimo system through the beam arrival angle, angle expansion of the interval between the antenna and the number of antennas, calculate the transmitter or receiver of the correlation matrix)

Chapter 2 and chapter 3 of digital communication system use matlab codes

Hopfield网络的TSP问题求解，能够出图的，哈哈啊哈哈哈哈哈哈哈哈(Hopfield network to solve TSP problems)

在matalab开发环境下的实现时域信号多尺度的分析，可用于信号的特征抽取和故障诊断(Multi-scale analysis of time-domain signal achieved in matalab development environment can be used for feature extraction and fault diagnosis signal)
