matlab航天工程工具箱，相信对航天，卫星仿真的人能有用(Matlab toolbox aerospace engineering, I believe the space, satellite simulation can be useful)

第13章 随机数生成.zip。是从书中光盘里直接拷贝的代码，放在这里，与大家共享，共同交流，希望对大家有帮助。(the random number generator.zip)

清音的对数幅度谱，短时过零率，平均能量，基音周期(Voiceless logarithmic amplitude spectrum, short-term zero crossing rate, average energy, pitch period)

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)

matlab生成m序列的函数 原来那个效率太低，主要是因为实际应用并不需要生成太长的m序列，加入了需求长度，能有效减少运行时间。25级的移位寄存器，运行了一个小时都没有出来一周期，我仅仅需要三千bit而已。改进版：(matlab generate a function of the original m sequence that efficiency is too low, mainly because of the practical application does not require generation of long m sequences, joined the demand for length, can effectively reduce the running time. 25 of the shift register, run for an hour did not come out one cycle, I just need more than 3000 bit. Improved version:)
