In multibody system dynamics,the orthogonality of eigenvector is the precondition to solve the dynamic response of system using the classical modal analysis methods.

The continuous eigenvector sample data of disturbance signal is extracted by wavelet transform and then dispersed by fuzzy C-means clustering algorithm to achieve a rule table of classification knowledge.

Because of the huge datasheet required by normal method, abundant calculation amount in Eigenvector improved method and not accurate enough coefficients in Walters improved method, we proposed a more simple and convenient method th.

Characteristic pickup,followed by the computation of n hydrocarbon characteristic indicators,which are used to forrn n-dimensional characteristic vector.

The authors mainly calculate characteristic root and characteristic vector of some normal polarizer s Jones matrix.

The spectrum of testing signal for the spot weld test is analyzed and the characteristic vector which can indicate the characteristics of the signal spectrum of ultrasonic signals for spot weld is obtained.

Under the conditions of preserving the meaning of the sample document, a feature vector which can best reflect the content of the sample document and is comparatively brief is found.

The feature vector of a fingerprint is formed by these average values in order.

A human face recognition algorithm based on the Hidden Markov Model (HMM) is presented For normalized face image,the algorithm extracts onedimensional human face feature vectors in 2DDCT.

Settlement observation results should be classified into settlement observation report in accordance with the requirement of the inspection result,what s different is that there should be necessary pictures in the report to describe the vector trait of data.
