MATLABtf函数 Tf函数用来建立实部或复数传递函数模型或将状态方程、或零级增益模型转化成传递函数形式。 sys=tf(num,den)命令可以建立一个传递函数,其中分子和分母分别为num和den。输出sys是储存传递函数数据的传递函数目标。 单输入单输出情况下,num和den是s的递减幂级数构成的实数或复数行向量。这两个向量并不要求...

This MATLAB function returns the numerator and denominator coefficients of the transfer function for the tf (Control System Toolbox), ss (Control System Toolbox) and zpk (Control System Toolbox) model objects or the array of model objects represented by
This MATLAB function converts the discrete-time filter System object to numerator and denominator coefficient vectors of the equivalent transfer function.
This MATLAB function returns numerators of S-parameters, Sij contained in num(i,j) and the denominator of the filter object.
