lsqnonlin-surface plot

Hello,

I would like to visualise using the surface plot if my optimisation using lsqnonlin found a global solution and if there are other minima. I have ODE system with 2 DE. I have obtained the vector of data for each DE equation (solved with the optimised values of the parameters)).

I've tried to search on the web, but I can't find anything relevant, which would work.

Thanks in advance

Sorry, I don't understand what you are trying to achieve. How many variables do you have for the plot? What is the response that you want to plot? For example, an ODE can often be visualized using a vector field plot, but not in more than 3 dimensions. But you have lsqnonlin on top of a system of differential equations, and I don't know what you would like to plot.
