y=dsolve('D2y+y=sin(t) * cos(30)','t');
C2=0;C3=0; %这是两个任意常数的取值
t=-10:.1:10; %自变量取值范围
x=eval(y);
plot(t,x);

matlab中 y=dsolve('Dy+a*y=b','y(0)=y0')
MATLAB中dsolve函数用法?
>> MATLAB中Y=dsolve('int(sqrt(1+(Dy)^2=Dy*(1-x)+y))','y(0)=0,Dy(0)=0','x')哪里错了?
求各路大神指导,MATLAB中:利用dsolve求解偏微分方程 的解(用符号计算).利用dsolve求解偏微分方程dx/dt=y,dy/dt=-x的解(用符号计算)
Matlab求常微分方程为什么错误 dsolve('Dy=-2x*y/(x^2+2*a)')这个matlab提示:Error using ==> dsolve at 126Can not use D as a variable in DSOLVE.
matlab用dsolve解常微分方程并画图,例如y'=1-y^2,y(0)=0.
matlab小问题matlab中如果我想求解常微分问题,会用到dsolve,但是怎么保证我算的那个函数的变量与我想要的一致?比如如下程序应该是:soln_1 = dsolve('Dy =3*x^2','y(2)=0.5') ans=x^3-7.500000000000000 现在却
MATLAB中dsolve解出的t是什么含义?我使用了dsolve(’Dy = sin(pi*x*y)‘);然后结果中:atan(2/(1+exp(2*t*pi*x+2*C1*pi*x))*exp(t*pi*x+C1*pi*x),-(exp(2*t*pi*x+2*C1*pi*x)-1)/(1+exp(2*t*pi*x+2*C1*pi*x)))/x/pi有t和c1两个量,c1想
在matlab中求三元微分方程组的问题有如下语句:dsolve('Dx=-y-z','Dy=x+0.1*y','Dz=2+z*(x-4)')无法解出,为啥?
matlab中求微分方程组通解dsolve('Dy=4*x-2*y','t','Dy=2*x-y','t')是错误的,那么,要怎么求关于t的通解呀?
matlab解不了这个简单的微分方程dequ='D2y=-GM/(y^2)'y=dsolve(dequ,'y(0)=R0','t')运行结果:Warning:Explicit solution could not be found.> In dsolve at 101怎么回事?
matlab 符号常微分y=dsolve('D2y-100*(1-y^2)*Dy=-y','y(0)=2,Dy(0)=0','x')哪里错了?
y=dsolve('D2y=(-9.8sin(y))','t')用matlab怎么解出y的轨迹?就是y对t的二阶导加上9.8siny=0
matlab(1-x)*y''=0.2*sqrt(1+y'^2) 输入y=dsolve('(1-x)*D2y-0.2*sqrt(1+(Dy)^2)=0',
matlab求解微分方程的答案出错求解的时候出现与题目无关的t,例如:y=dsolve('Dy=x')得 y =C2 + t*x
求教如何使用Matlab编程时解决微分方程中变量替换问题?x和y都是t的函数 x和y的关系为 x=2y-3dsolve('Dy=1/(x+y)','T(0)=0','t') 把微分方程中x由2y-3代入,解微分方程,得出y(t)然后根据 x和y的关系式,求
这个matlab程序哪儿有问题呢?x=dsolve('D2x+2*0.25*Dx+0.4^2*x=1.0*sin(0.5*t)','x(0)=1','Dx(0)=-1','t'); t=1:0.01:3;y=diff(x,2); t;y这是以上的程序,y是一个关于t的方程,即y=y(t),我想求出t=1:0.01:3时,y相应的值,但是
