我通过这段代码创建了符号矩阵“T”：

for row = 1:n
for col = 1:m
    T(row, col) = sym(sprintf('T_%d_%d', row, col));
end
end

对于 n=4 ， m=4 结果是：

[ T_1_1, T_1_2, T_1_3, T_1_4]
[ T_2_1, T_2_2, T_2_3, T_2_4]
[ T_3_1, T_3_2, T_3_3, T_3_4]
[ T_4_1, T_4_2, T_4_3, T_4_4]

对于 n=12, m=12 结果是：

[ T_1_1, T_1_2, T_1_3, T_1_4, T_1_5, T_1_6, T_1_7, T_1_8, T_1_9, T_1_10, T_1_11, T_1_12]
[ T_2_1, T_2_2, T_2_3, T_2_4, T_2_5, T_2_6, T_2_7, T_2_8, T_2_9, T_2_10, T_2_11, T_2_12]
[ T_3_1, T_3_2, T_3_3, T_3_4, T_3_5, T_3_6, T_3_7, T_3_8, T_3_9, T_3_10, T_3_11, T_3_12]
[ T_4_1, T_4_2, T_4_3, T_4_4, T_4_5, T_4_6, T_4_7, T_4_8, T_4_9, T_4_10, T_4_11, T_4_12]
[ T_5_1, T_5_2, T_5_3, T_5_4, T_5_5, T_5_6, T_5_7, T_5_8, T_5_9, T_5_10, T_5_11, T_5_12]
[ T_6_1, T_6_2, T_6_3, T_6_4, T_6_5, T_6_6, T_6_7, T_6_8, T_6_9, T_6_10, T_6_11, T_6_12]
[ T_7_1, T_7_2, T_7_3, T_7_4, T_7_5, T_7_6, T_7_7, T_7_8, T_7_9, T_7_10, T_7_11, T_7_12]
[ T_8_1, T_8_2, T_8_3, T_8_4, T_8_5, T_8_6, T_8_7, T_8_8, T_8_9, T_8_10, T_8_11, T_8_12]
[ T_9_1, T_9_2, T_9_3, T_9_4, T_9_5, T_9_6, T_9_7, T_9_8, T_9_9, T_9_10, T_9_11, T_9_12]
[ T_10_1, T_10_2, T_10_3, T_10_4, T_10_5, T_10_6, T_10_7, T_10_8, T_10_9, T_10_10, T_10_11, T_10_12]
[ T_11_1, T_11_2, T_11_3, T_11_4, T_11_5, T_11_6, T_11_7, T_11_8, T_11_9, T_11_10, T_11_11, T_11_12]
[ T_12_1, T_12_2, T_12_3, T_12_4, T_12_5, T_12_6, T_12_7, T_12_8, T_12_9, T_12_10, T_12_11, T_12_12]

创建 T 矩阵后，我需要根据 T 求解其符号变量为 T_i_j 的 m*n 线性方程。

通过使用求解函数，T_i_j 的结果按字母顺序排序如下：

4*4：（没问题）

  T_1_1: [1x1 sym]
T_1_2: [1x1 sym]
T_1_3: [1x1 sym]
T_1_4: [1x1 sym]
T_2_1: [1x1 sym]
T_2_2: [1x1 sym]
T_2_3: [1x1 sym]
T_2_4: [1x1 sym]
T_3_1: [1x1 sym]
T_3_2: [1x1 sym]
T_3_3: [1x1 sym]

T_4_1: [1x1 sym]
T_4_2: [1x1 sym]
T_4_3: [1x1 sym]
T_4_4: [1x1 sym]

但对于 12*12 或更高的结果是：

**我如何对下面的 12*12 的结果进行排序？？？（通过 for 循环等）（根据 T 矩阵的行进行类似的排序 4*4

T_1_1,
T_1_2,
T_1_3,
T_1_4,
T_1_5,
T_1_6,
T_1_7,
T_1_8,
T_1_9,
T_1_10,
T_1_11,
T_1_12,
T_2_1,
T_2_2
T_2_3
.
.
.
T_3_1
T_3_2
.
.
.

这对我来说是非常必要的。请有任何想法。最良好的问候！艾哈迈德

用这个：

T(row, col) = sym(sprintf('T_%03d_%03d', row, col));

它会将您的数字零填充到三位数，因此排序将再次执行正确的操作。
