各位前辈，小白在此请教：已经求出ei,fi,i=1,8的向量，想用这64个元素，组成一个矩阵，下面代码也能实现这一功能，感觉有点不精练，请教前辈有没有别的方法可以实现。
e1 = {e11, e12, e13, e14};
e2 = {e21, e22, e23, e24};
e3 = {e31, e32, e33, e34};
e4 = {e41, e42, e43, e44};
e5 = {e51, e52, e53, e54};
e6 = {e61, e62, e63, e64};
e7 = {e71, e72, e73, e74};
e8 = {e81, e82, e83, e84};
f1 = {f11, f12, f13, f14};
f2 = {f21, f22, f23, f24};
f3 = {f31, f32, f33, f34};
f4 = {f41, f42, f43, f44};
f5 = {f51, f52, f53, f54};
f6 = {f61, f62, f63, f64};
f7 = {f71, f72, f73, f74};
f8 = {f81, f82, f83, f84};
Join[{e1}, {e2}, {e3}, {e4}, {e5}, {e6}, {e7}, {e8}] // MatrixForm
Join[{f1}, {f2}, {f3}, {f4}, {f5}, {f6}, {f7}, {f8}] // MatrixForm
Join[%, %%, 2] // MatrixForm

一开始如果把e1写成e[1]至少可以方便后面操作，而且在输入的时候可以有意识的带有结构，比如m={{},{},{}}。

Join[{e1}, {e2}, {e3}, {e4}, {e5}, {e6}, {e7}, {e8}]和{e1, e2, e3, e4, e5, e6, e7, e8}有啥区别

Clear["Global`*"];
e[i_] := Table[
ToExpression["e" <> IntegerString[i] <> IntegerString[j]], {j, 1,
4}];
f[i_] := Table[
ToExpression["f" <> IntegerString[i] <> IntegerString[j]], {j, 1,
4}];
Table[e[i], {i, 1, 8}] // MatrixForm
Table[f[i], {i, 1, 8}] // MatrixForm
Table[f[i]~Join~e[i], {i, 1, 8}] // MatrixForm

……你果然最后准备压平啊。联动：https://tieba.baidu.com/p/6849439079
