对OFDM系统的发送端和接受端信号的频谱进行仿真，还有星座图(On the OFDM system transmitter and the receiving end of the spectrum signal simulation, there are constellation)

该代码仅计算了一个101×101尺寸的Gabor函数变换，得到均值和方差。代码采用两种卷积计算方式，从结果中可以看出，快速傅立叶变换卷积的效率是离散二维叠加和卷积的近50倍。 (The code is only the calculation of a 101 × 101 size Gabor function transformation, the mean and variance. Convolutional code using two methods of calculation can be seen from the results, fast Fourier transform convolution efficiency are two-dimensional discrete convolution superposition and nearly 50 times.)

MATLAB的一些经典算法，大家看看有没有用！(MATLAB' s some classic algorithms, we see no use!)

对matlab中的robotics toolbox中的函数功能及作用进行详细解说，方便初学者掌握函数。(Robotics toolbox for matlab in the function and role function in the detailed explanations, easy for beginners to master functions. )

利用重力剖面反演水平圆柱的边界及位置，程序抗干扰能力较差，模型计算加入噪音严重影响结果，但可作为算法参考并加以改进。(Tilt-Depth for gravity profile over horizontal cylinder)

Box-Muller变换，将[0,1]均匀分布转换为[0,1]高斯正态分布，在matlab中也可用randn函数生成正态分布。变换的思想可用于其他没有正态分布随机函数的编程语言（如C）()
