A general proof of consistency of the ols estimators from the multivariate regression case can be shown through matrix manipulations 多元回归中ols估计量的一致性的证明可以通过矩阵运算得到。
This approach only requires the noise inputs to be energy - bounded instead of gauss white noises . the main results can be expressed by lmi after some matrix manipulations 该方法不需要限定系统的噪声输入信号为高斯白噪声,而只要求噪声信号为能量有界。
Numeric - symbolic technique is introduced in the procedure of resultant elimination , procedure of number - spobol manipulation is transformed into that of matrix manipulation . because joini variables are treated as symbols and all structure paramcters are treated as real nuxnbers , the complexity of derivation for input - output equaion is reduced . the soluton is verified with a numerical example , its rsults withoot extraneous roots agree with the original equaions 消元过程中引入了数字-符号方法,将结构参数处理为数值量,将关节变量处理为符号量,将数字、符号推导过程转化为了矩阵运算过程,由于结构参数以数值量的形式出现在方程推导中,降低了符号推导的难度,符号推导不需要复杂的符号处理软件的支持。
