A general proof of consistency of the ols estimators from the multivariate regression case can be shown through matrix manipulations 多元回歸中ols估計量的一致性的證明可以通過矩陣運算得到。
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 該方法不需要限定系統(tǒng)的噪聲輸入信號為高斯白噪聲,而只要求噪聲信號為能量有界。
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 消元過程中引入了數(shù)字-符號方法,將結構參數(shù)處理為數(shù)值量,將關節(jié)變量處理為符號量,將數(shù)字、符號推導過程轉化為了矩陣運算過程,由于結構參數(shù)以數(shù)值量的形式出現(xiàn)在方程推導中,降低了符號推導的難度,符號推導不需要復雜的符號處理軟件的支持。
