Hi to everyone, I'm trying to plot a 3D graph on MATLAB but I do not know how. The function that I want to plot is: y=fminbnd(@(x) wei(x,shape,scale,tw,tf),x0,x1). I would like to plot the minimization of the function wei (y) in function of the shape and the scale. Wei is a function that I...

In fact, my function is this one: I posted a simplified one before, can I still express this one with a well-known formula? Thanks

In this formula, the summaton begins at i=0, while in my case it's i=1. How can I solve that? Thanks

Thanks for your advice, so far the best I've received. Can I use this formula? By the way, how do you introduce formulas in this forum?

Hi Ssnow, x is a real, I'm working on a domain and i do not have any constrains more.

If we forget about the relationship between i and T, how would you optimize it?

Apologies, I wanted to say that it goes from i=1 to inifinite. I will reformulate my question so you can understand it better. I want to maximize this function: And x is related to i as follows; i=T/x, where T is a constant. Due to the nature of the problem, i is an integer. Thanks for your...

Yes, it is from i to ∞, but if I want to optimize it I guess that I will have to set a bound. And yes, the summation corresponds to what you have posted. Let's say that i is related to x as follows: i=T/x, T is a time. Therefore, x determines i.

Hi to everyone, I'm optimizing a nonlinear function but I'm struggling to achieve it. The function is the following: X and i are relationed so i doesn't go to infinite. Do you have any idea how to maximize this function? Thanks in advance, Eric
