欧拉办法就是用数值近似的办法得到微分方的近似解如下图，最简单的欧拉办法下一个yn+1点的值近似由当前点的值f(xn,yn)和x增量h得到很容易就能够根据递推公式一步一步计算出从初始点x0一定范围的数值近似解这里只给出题目a的解，后面的应该可以很容易举一反三地解决h=0.025;x0=1;xend=1.1;...
Forward Euler (默认)选择正向矩形(左恻)逼近。此方法最好是 小的采样时间,奈奎斯特限制控制器的带宽相比要大得多。较大的采样时间,在the Forward Euler method可能会导致不稳定,即使是在持续时间里,离散系统是稳定的。Backward Euler选择向后矩形的(右侧)逼近。如果您正在生成代码,使用Simulink编码器软件或定点工具...

then midpoint method to solve for a value. I call on a different mfile that I have named "dydtsys.m" where I gather the equations needed for this project. Any and all help would be appreciated. I have tried to rename the 'unrecognized function or variable' as euler, eulsys, euler...
Desire is to use the Euler Method – Aerospace to determine the Psi, Phi, and Theta values, the Psidot, Phidot, and Thetadot values, and the q,p, and r values by importing the .csv file and running a script. Key to my understanding is how the script is written; if someone would...
