用逆累积分函数算出随机变量X满足拉普拉斯分布的随机数 (Random variable X is calculated using the inverse tired integral function to meet the Laplace distribution of the random number)

说明：  齿轮箱故障诊断中振动信号是非线性、非平稳的，所以在分析振动信号之前需要对信号进行平稳化处理，该段是EMD分解的程序。(Gearbox Fault Diagnosis vibration signal is nonlinear, non-stationary, so before analyzing vibration signals the need for a smooth signal processing, the segment is the EMD program.)

This function finds the forward kinematics of the RA-01 Robotic Arm made by Images SI, Inc. The RA-01 has five degrees of freedom. This funciton outputs two vectors. The first vector is the forward kinematics of the central position of the end effector, while the second vector is the forward kinematics of a finger of the end effector (a gripper). Note that it does not matter which finger it is as the position of one finger is simply the negative of the other hence, the value gotten for the y-direction is actually "plus or minus y".

The following Matlab project contains the source code and Matlab examples used for 2d wave equation. An interactive demo of the 2D wave equation
