Applied Optimization - Matlab 'fminsearch' with Two Variables

Here's how to use the fminsearch function in Matlab with functions of two variables. I show you how to make a contour plot of a sample function and how to find the minimum point using fminsearch.

It was very helpful to teach in detail so that even a beginner like me can do it easily.

I was struggling for over a hour with the first syntax..... thank you so much !

You all prolly dont give a damn but does anybody know of a tool to get back into an instagram account?
I stupidly lost the login password. I love any tips you can give me

@Khari Sterling thanks so much for your reply. I got to the site thru google and im waiting for the hacking stuff now.
I see it takes a while so I will get back to you later when my account password hopefully is recovered.

@Khari Sterling It did the trick and I actually got access to my account again. I'm so happy:D
Thank you so much, you saved my ass!

what is the creepy picture underneath the one of oscar wilde?

[@gurpritsingh2339]

is it necessary to plot a contour before executing fminsearch?

[@abdullahalmosalami2373]

The contour plot is just there to help visualize where the max of the function probably should be.

How can I visualize the Nelder Mead Algorithm (=fminsearch) with "contour" (and "line")? Nice video btw! Greetings from Germany. Is there a way to adjust the contraction-, expansion- and reflectionparameter?

For all other lazy guys among us, here is the function:
f=@(x1,x2) 1/7*sqrt(2500+x1^2) + 1/4*sqrt(400+(x2-x1)^2) +1/2*sqrt(900+(100-x2)^2)
