数值分析，上机题目，求解方程组十分方便 数值分析，高斯公式， 求解方程组十分方便(Numerical analysis, the machine topic is very convenient for solving equations numerical analysis, Gaussian formula is very convenient for solving equations)

fir滤波器，7、8、13、14，对信号进行alpha、betagamma滤波，调用方法 Hd = fir_alpha 滤波后信号 = filter(Hd,原信号) 得到的信号是时域信号，plot直接显示(Fir filter, 7, 8, 13, 14, alpha filter for signal method is called Hd = fir_alpha After filtering signal = filter (Hd, the original signal) Signal is time domain signals, the plot showed directly)

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".

This control system has been successfully applied in some 750mm hot strip mill. The actual record curves indicate that the dynamic feedforward strategy can do well in controlling the tail temperature. And the FuzzyPI-Smith system can get better dynamic characteristic and effectively overcome the problems by pure lag with the traditional
