matlab语言实现计算全息，修正离轴灰阶显示(the matlab language calculation holographic corrected off-axis grayscale display)

关于matlab非常好的一本书，讲的非常的详细，特别适合初学者(A very good book on matlab, in a very detailed, especially for beginners)

生成PN序列（伪随机噪声序列），阶数包括2阶，3阶，4阶，5阶，6阶，7阶，8阶。并在前面补0后形成相应的2的幂次长的序列。(Generated PN sequences (pseudo-random noise sequence), including the orders of 2 order, 3 order, 4 order, 5 order, 6 order, 7 order, 8 order. And fill in front of 0 after the formation of the corresponding power of 2-long sequence.)

车辆信号的震动信号的滤波、幅值以及能量分析，信号是利用测试台采集回来的。(Vehicle vibration signal filtering signals, amplitude and energy analysis, the signal is the use of test collection back.)

L-system and IFS are used to the plant s simulation. In this package the theories of L-system and IFS were concisely described. The excellence and short of constructing Fractal image with L-system or IFS were discussed. So a method was put forward in this package. At last the three-dimension tree model ceatrs successfully based on L-system and IFS.

QPSK signal matlab code

利用蚂蚁算法求解最短路径问题，稍作修改既可以用于移动机器人路径规划当中。(Ants use the shortest path algorithm to solve the problem, with some slight modifications can be used in mobile robot path planning among them.)

CDMA通过gold7和gold31来进行编码。并比较不同编码下的CDMA的性能(cdma performance via different length of gold encode )
