批量生成变量赋予随机值

青青子衿

1. Clear["`*"]
2. lst1 = Flatten[
3.    Table[Symbol[Evaluate["a" <> ToString[i] <> ToString[j]]], {i, 0,
4.      3}, {j, 1, 3}]];
5. lst2 = Flatten[RandomReal[{-2, 2}, {4, 3}]];
6. data1 = {lst1, lst2}
7. MapThread[(Clear[#1]; #1 = #2) &, data1]

请问上面的
Flatten[RandomReal[{-2, 2}, {4, 3}]]
是否可以写成
RandomReal[{-2, 2}, 12]

请问Clear["`*"]和Clear["Global`*"]是否等效
