The article firstly work out the eigenvalues of the matrix,then we decide the jordan block number of each eigenvalues and the progression of each Jordan block,this produces another method to work out matrix Jordan canonical form of matrix.

• 文章通过先求矩阵的特征值；然后确定属于每一个特征值的若当块的个数和每一个若当块的级数来给出矩阵若当标准形的另一种求法.
