马尔科夫链的matlab仿真,马尔可夫模型（Markov Model，MM）是统计模型，它用来描述一个含有隐含未知参数的马尔可夫过程。(Matlab simulation of Markov chains, Markov models (Markov Model, MM) is a statistical model, which is used to describe an unknown parameter containing hidden Markov process.)

matlab对一幅图像，采用半径值为20、80、200的截止频率进行理想低通滤波，观察其结果。要求给出原图像及相应的付利叶频谱图和滤波结果(For an image, using the radius value of the cutoff frequency 20,80,200 ideal low-pass filter to observe the results. Required to give the original image and the corresponding Fourier spectrum and filtering results)

用FFT计算信号的功率谱密度时，需要先计算FFT，再计算双边谱密度，然后计算单边谱密度。在matlab里注意FFt要除以采样点数，计算双边谱时要注意除以频率分辨率。 ( When calculated using the FFT power spectrum density signal, you need to calculate the FFT, and then calculate the bilateral spectral density, and then calculate the unilateral spectral density. In matlab in Note FFt divided by sampling points should be noted when calculating the bilateral spectrum divided by the frequency resolution.)
