Hello, i have this function to pass to lsqnonlin :
[val,Jac] = myfunction(x,par1,par2,par3)
my function computes already the Jacobian that im planning to pass to slqnonlin and is essential.
x is the optimization variable and par1,par2... are constant parameters required to evaluate the function and are computed separately.
The problem then is how i declare x as the only optimization variable?
I can't use function handle otherwise i would lose my multi ouput;
I can't declare par1,par2,... as globals cause myfunction has parallelization in it;
I could pass the code to evaluate pars into myfunction but it would add not necessary heavy computation into each iteration of lsqnonlin which i'd like to avoid;
Any other ideas? Thank you
