MATLAB解微分方程：a=105.52 b=0.059 dsolve('D2y+2783.83*(1-2*b*cos(a*t))*y=0','y(0)=1','Dy(0)=0','
没有解析解,请问数值解怎么求

ODE45
或ODE23
即龙格库塔法
话说没有分么?
再问： ��ܽ��а�
再答： ��Ž��һ�£� >> dy=inline('[y(2);2783.83*(2*0.059*cos(105.52)-1)*y(1)]','t','y');>> ode45(dy,1,[1 0])

y-t��ͼ��Ϊ��

再问：多谢，还可以再问你个问题吗，矩阵形式怎么 clear all n=2; EI=4.2063e6; L=7; M=[m11,m12;m21,m22]; K=[k11,k12;k21,k22]; S=[s11,s12;s21,s22]; DL=inline('[x(n+1:end,1); inv(M)*(-K*x(1:n,1)-(98264*cos(79.865*t))*S*x(1:n,1))]',... 't','x','flag','n','M','K','S'); 请看私信。。。，多谢了
