关于#matlab#的问题：其他的量是变量我已设置好了模块，但不会合起来解这个方程

syms y1(t) y2(t)
eqn1 = diff(y1)==-2*y1+4*y2;
eqn2 = diff(y2)==3*y1-5*y2;

[eqn1,eqn2]

cond1 = y1(0) == 1;
cond2 = y2(0) == 1;

conds = [cond1 cond2];

[Sol_y1Sol_y2] = dsolve([eqn1, eqn2],conds)

% 提取y1, y2解析解
Sol_y1 = simplify(Sol_y1Sol_y2.y1)
Sol_y2 = simplify(Sol_y1Sol_y2.y2)
