The method developed in this paper using the global matrix is an improved version of Nayfeh's matrix method.

1 1 880 m3 BF was trouble in furnace condition during the recovery period after repair work,the main reasons were as follows: much equipment fault,irrational burden distribution matrix,increasing of Al2O3 in slag,operation fault and so on.

In this way,the burden distribution matrix wa.

Knowledge reduction algorithm based on elementary row transformation of Boolean matrix;

Boolean matrix representation of rough set in decision table;

This paper defines the Boolean matrix,puts forward the standard model of tree,uses the standard model to generate the defining method and the algorithm of a tree,and then realizes the algorithm with computer.

Firstly, all the samples are projected to the nonzero space of the total scatter matrix.

Then,an image scatter matrix is constructed using the reshaped image matrixes and its eigenvectors are derived for image feature extraction.

The generation matrix of the GPCA is analyzed, and the between-class scatter matrix is redefined by introducing a radical basis function, so classification features are obtained by adjusting the coefficient of the function.

A seismic casualty forecast method which is directly related to the building earthquake damage is established by introducing the index of seismic casualties and seismic casualty probability distribution matrix.

In this paper, we study the symmetry on distribution matrix of order statistic of discrete type random variable.

According to the distribution matrix of discrete random variables,the necessary and sufficient conditions of independence about two and three dimensional discrete random variables,the judge method on independence of discrete random variables and its application were given.
