阅读以下说明及Visual Basic程序代码，将应填入(n)处的字句写在对应栏内。[说明]本程序提供了三阶矩阵加、减及乘运算的功能。用户单击“生成操作数”按钮将随机生成两个矩阵(即操作数1和操作数2)，再单击某一矩阵运算按钮后，程序将输出相应运算的结果。程序运行界面如下：开发过程中，界面上从左至右三个文本框分别取名为Text1至Text3，“生成操作数”按钮名为 CmdNew，“+”、“-”和“*”构成按钮控件组，分别名为CmdOperate(0)、CmdOperate(1)和CmdOperate(2)。已知n阶矩阵加、减法运算法则是对应位置的元素相加、减；n阶矩阵的乘法C=AB有公式：Cij=AilBij+AilBij+…+An1Bnj其中记号Xij表示矩阵X第i行第j列上的元素。程序使用的主要变量是三维数组matrix(3，3，3)，其元素matrix(i，j，k)代表第i个矩阵j行k列上的元素，这里i，j，k均从0开始计数，第0、1、2个矩阵分别表示操作数1、操作数2和结果矩阵。代码中用到的子过程及其功能说明如下：(1) Sub newMatrices():随机产生矩阵运算的两个操作数；(2) Sub printOut(txt As TextBox, i As Integcr):定义矩阵i向文本框txt的输出格式；(3) Sub operate(operation As String):计算并输出矩阵运算结果。[Visual Basic代码]Dim matrix(3, 3, 3) As IntegerSub newMatrices()……… End SubSub printOut(txt As TextBox, i As Integer)……… End SubSub operate(operation As String)Dim i, j, k As IntegerFor i = 0 To 2For j = 0 To 2(1)Case"+": matrix(2, i, j) = matrix(0, i, j) + matrix(1, i, j)Case"-": matrix(2, i, j) = matrix(0, i, j) - matrix(1, i, j)Case"*"matrix(2, i, j) = 0For k = 0 To 2matrix(2, i, j) = matrix(2, i, j) +(2)NextEnd SelectNextNextprintOut (3)End SubPrivate Sub CmdNew_Cliek() ’“生成操作数”按钮的单击事件响应代码(4)printout Text1，0printout Text2，1End SubPrivate Sub CmdOperale_Click(Index As Integer) ’矩阵运算按钮组的单击事件响应代码operate CmdOperate(Index).(5)End Sub
