MATLAB: Lagrange Equations M-file

lagrange equations

Hi all..

Can you help me about making Lagrange Equations at M-file? sorry i'm noob.. Thanks 😀

Best Answer

Save this to a file with a .m extension

function  [out1,out2,...outM] = LagrangeEquations(arg1, arg2,arg3,...,argN)

Also try some online tutorials, e.g.,

MATLAB: Saving an interpolated function to an m-file

Hi,

To my understanding, you want to save the custom interpolation as function to be available for further evaluation.

For that you can write the code as a MATLAB function.

Here is a sample version for the example code you provided

function res = f(x) 
    xd = -1:0.01:1; 
    yd = xd.^2;  
    res =  interp(xd, yd, x); 
end

Hope this helps.

here is a nudge to solving your problem

syms x y L
d = ???                   % for you to fill out; distance from (-1,0)
g = d+L*(x^2+2*x-y)       % constraint for given parabola
% additional operations here

show some effort, and some additional help may be forthcoming
