Open in MATLAB Online I want to do the first part of Langrange equations differentiaton, but I'm stuggling with d/dt(dL/dalpha_dot). I use symsalpha(t) to differentiate with time r_d=diff(r,t) and then use L_new=subs(L,diff(alpha(t),t),ald) ...

How to make this Lagrange formula vectorized work for all Ln? This is only for L3閉鎖済み:MATLAB Answer Bot
If you do this without event functions and a restart of the integration, you try to integrate a non-smooth function. This collides with the specifications of standard ODE functions such that the results has eitehr an extremely poor accuracy or the integration might even stop. Se...
MATLAB Online에서 열기 Im new to matlab and i am trying to make a differential equation solver, i have a textfield where i input the equation in, and i have tried str2sym but it doesnt seem to work, what am i doing wrong? should i try with a...
in the equations above a,b,c,d,e and f are the numerical known values (0.543 for example). So we have 6 equations with 5 unknowns as L, Z, M, T and B. Can you please give me cues how to solve the equations to find these unknowns using MATLAB. ...
I am working with Lagrange Eqautions and hence I need to differentiate this way. I already used the idea of subsitution by a variable but I was not really sure if that was the right way. Hence wanted to know if there was a better way around this problem Walter Roberson on 26 Feb...
