请你写段代码，把['A2,B1,C3,D3,E1,F1,H1' 'A2,B1,C3,D3,E1,F1,H1']转换为[['A2','B1','C3','D3','E1','F1','H1'],['A2','B1','C3','D3','E1','F1','H1']]

好的，以下是将字符串数组转换为二维字符串数组的Python代码：

# 定义字符串数组
str_arr = ['A2,B1,C3,D3,E1,F1,H1', 'A2,B1,C3,D3,E1,F1,H1']

# 定义结果列表
result = []

# 对每个字符串进行处理
for str in str_arr:
    # 将字符串按逗号分割为列表
    str_list = str.split(',')
    
    # 添加到结果列表中
    result.append(str_list)
    
# 输出结果
print(result)

输出结果为：

[['A2', 'B1', 'C3', 'D3', 'E1', 'F1', 'H1'], ['A2', 'B1', 'C3', 'D3', 'E1', 'F1', 'H1']]

matlab怎么把三元二次方程组求解

在MATLAB中，你可以使用`solve`函数或者`linsolve`函数来解决三元二次方程组。这里假设你有一个标准形式的三元二次方程组，例如：

\[ a_1x^2 + b_1xy + c_1xz + d_1x + e_1y^2 + f_1yz + g_1z^2 + h_1x + i_1y + j_1z + k_1 = 0 \]
\[ a_2x^2 + b_2xy + c_2xz + d_2x + e_2y^2 + f_2yz + g_2z^2 + h_2x + i_2y + j_2z + k_2 = 0 \]
\[ a_3x^2 + b_3xy + c_3xz + d_3x + e_3y^2 + f_3yz + g_3z^2 + h_3x + i_3y + j_3z + k_3 = 0 \]

解决方案如下：

syms x y z % 宣告变量为符号

% 假设a-h都是矩阵，k是一个向量
eqns = [a1*x^2 + b1*x*y + c1*x*z + d1*x + e1*y^2 + f1*y*z + g1*z^2 + h1*x + i1*y + j1*z + k1;
        a2*x^2 + b2*x*y + c2*x*z + d2*x + e2*y^2 + f2*y*z + g2*z^2 + h2*x + i2*y + j2*z + k2;
        a3*x^2 + b3*x*y + c3*x*z + d3*x + e3*y^2 + f3*y*z + g3*z^2 + h3*x + i3*y + j3*z + k3];

solutions = solve(eqns, [x, y, z]) % 解决方程组

这将返回所有满足方程组的解。注意如果方程无解、有无穷多解或者解为复杂表达式，`solve`可能会给出相应提示。
