我是 MATLAB 刚接触 Python 的新手。我现在在用 Python 求解方程组时遇到问题。例如，在Matlab中
R = solve( a1*[x1; x2] == [y1;y2], ...
a2*[x3; x4] == [y3;y4], ...
a3*[x5; x6] == [y5;y6], ...
x2 == y3, x3 == y2, ...
x4 == y5, x5 == y4, ...
[ x2 x3 x4 x5 ...
y1 y2 y3 y4 y5 y6]... % unknown
);
y1 = simplify(R.y1);
y10 = simplify(R.y10);
a1..a5是系数y1 y10是我需要求解的，它们应该是求解后的符号表达式。如何在 Python 中做到这一点？
