Also note that the matrix row identified in the first column in the data set is ALWAYS smaller than the corresponding matrix column identified in the second column of the data set.
还需注意数据集中第一列所确定的矩阵行值必须小于相应矩阵第二列所确定的行值。
So 2 and minus 1 in the first row, minus 1 and 2 in the second row, that is the matrix.
所以2和- 1在第一行，- 1和2在第二行，这就是一个矩阵。
Each row in the OV-3 matrix represents an IER, which is made up of characteristics of the data transferred between roles and objects in an interaction from the OV-6c sequence diagrams.
OV - 3矩阵中的每一行表示一个IER，由在OV - 6 c序列图的交互中的角色和对象间转移的数据的特征组成。
