Hey Satendra, Great Video!

I was wondering if you could provide a more detailed description of the fval vector and maybe show us graphically what this vector means? Thanks!

Pls stop @2:40, The most of the queries i got are related to this step. Please note that the variable in myfun(x), is "x" and so i have to choose my other variables as x(1) & x(2)...Again x1 or x2 is not allowed. They must be in the same as show in the video.
Thanks for visiting me.

Is it necessary to add a guessed soluctions vector?

[oyindas]

is your x0 the guesses for the function? Thanks

Hello Satendra,
I need some help solving a nlp maximization equation in matlab. Can you please help?

[capper]

what software do you use to record screen and which microphone ?
Thanks in advance.

Hey really nice video :)

I hope you can help me:
I want to know the solution for x1 of the following function (i know u1, u2, u3):



What i have to write ?

I know i need to use fsolve but i have really absolutly no idea what the code looks like.

I need this to insert it as Interpreted Matlab function with u1, u2 and u2 as input.

I did same your work
but I got this Error
