| Abstract: | In this paper,a real matrix is looked as a system of column vectors and the concept for the angle condition number of the system of column vectors is defined,also the relationship beteen the angle condition number of the system of column vectors and the spectral condition number of the matrix is investigated,and so some advonteges of angle condition number are pointed out. |
