怎么用matlab dsolve求下面微分方程组的解,求解答。附方程和错误提示 5
[x1,x2,x3,x4,x5]=dsolve('Dx1=314.16*x2','Dx2=0.0041*x1-0.5316*x2-0.0309*x3-0.0106*x4-...

初始值是乱设的，具体问题中需要某个不为0，如'x1(0)=1‘。谢谢 展开

没有解析解，改用ode数值求解吧

数值解求出来的是某些时刻的值，还需要对其中一些变量求积分，请问该怎么做
追答
选好变量和被积函数，数值积分

是的。传统上，对于符合要求的内毒素检测，最终用户必须从标准内毒素库存瓶中构建至少一式两份三点标准曲线；必须有重复的阴性控制；每个样品和PPC必须一式两份。有了Sievers Eclipse内毒素检测仪，这些步骤可以通过使用预嵌入的内毒素标准...
