How do i write the code of lagrange multiplier in lagrange function ? Because the lagrange multiplier is a varible ,like x,y,z.not a random value,so for example,the function i want to optimize is as below
![lagrange.PNG](https://www.mathworks.com/matlabcentral/answers/uploaded_files/201334/lagrange.png)
then how do i write the matlab code of lagrage multiplier ? because there are lots of a_k and b_k,and they all should be calculated,so i can't just use "rand" to produce them.
Does anyone know how to write the code of this? or is there any reference i can refer?

Which of the K k's do you mean when you define your objective function as
min: x_k^2+y_k^2
?

Hi,
here is an example, which you can use to learn how you can tackle this problem in Matlab:

I beg to differ. That link didn't lead to a solution for dealing with nonlinear constraints in langrange multipliers. Please show me one when you find it.
