谁可以帮我看下这个vb的小程序呀
要求：
（1）将两个矩阵相乘，结果放入矩阵C中（注意矩阵的乘法规则）
（2）统计矩阵C中最大值和下标以及最小值和下标
（3）求矩阵A两条对角线元素的平均值
（4）将矩阵A按列的次序把各元素放入一维数组D中，显示结果。
下面是我自己做的,可是矩阵AB都显示不出来,所以后面也无法检验....

'帮你改了,不过,由于习惯问题,连变量名也改了:)
'你自己对比着看,看看你的哪错了吧
'我比较习惯用label来显示不需要改动的量，
'label1，2，3分别显示数组a,b,c三个矩阵。按行顺序显示。
'加“，”号区分各数，方便查看。
'label4,5显示最大，小数：max,min
'label6显示矩阵a的对角平均数
’label7按顺序显示一维数组d()
