matlab中在哪查看dsolve得出的解
我的程序为:
syms a b t n
>> a=0.0099.*(coth(0.5)-cot(0.05).*exp(-0.1.*t).*(0.1.*cos(t)-sin(t))-0.03184.*cos(t).*symsum(exp(-n.*6.28.*t)./(n-0.015923),n,0,Inf));
>> b=0.0099.*(1-exp(-0.1.*t).*cos(t)-0.1.*exp(-0.1.*t).*sin(t));
>> s=dsolve('Dy11=-2*(a+b)*y11+(a-b)*(y22+y33),Dy22=(a+b)*y11-2*a*y22+(a-b)*y44,Dy33=(a+b)*y11-2*a*y33+(a-b)*y44,Dy44=(a+b)*(y22+y33)-2*(a-b)*y44,Dy55=-2*a*y55','y11(0)=0.25,y22(0)=0.25,y33(0)=0.25,y44(0)=0.25,y55(0)=0.25')
上述程序都运行正确.但matlab给出的结果是:
s =
y11:[1x1 sym]
y22:[1x1 sym]
y33:[1x1 sym]
y44:[1x1 sym]
y55:[1x1 sym]
没有具体的答案.各位大侠支支招

到workspace里面点s,一级一级点下去.
