设有矩阵a且a=执行下列语句后矩阵c和a的结果分别是什么?
() FOR i:= TO DO
FORj:= TO DO c[ij]:=a[a[ij]a[ji]]
() FOR i:= TO DO
FORj:= TO DO a[ij]:=a[a[ij]a[ji]]【浙江大学 三 (分)】
设矩阵A为
()执行语句
FOR i:= TO DO
FOR j:= TO DO ①
C[ij]:=A[A[ij]A[ji]]
结果C矩阵的值是什么?
()所选择的下标ij的次序有关系吗?
()在语句①中用A代替CA的结果值是什么?
()对ij这对下标取反序即
()()()……()()()
重复执行()把所得结果与()中所得结果作比较【吉林大学 二 (分)】
