How to reply to a message?

This is a general question for the mathworks.com webpage. I hope this is the right place to ask this question. I looked up for some information but couldn't find anything.

My problem is when I want to reply to a message I always get linked to "MathWorks Account - Edit Profile". Is this an error of the webpage or am I doing something wrong.

What do you mean by ‘reply to a message’?

If you want to send a personal message to someone who has posted here, you will get linked to the person’s profile page. If the person allows personal messages, there will be a small ‘envelope’ symbol near the position for the person’s avatar. If the ‘envelope’ symbol is not there, you can see if the person has a similar profile page in the File Exchange. (Most have File Exchange personal message links because they want feedback on their File Exchange contributions.) Use that to send your message.

‘When you open this link you'll see in the message header "Reply to this message" when I click this button a new website opens, MathWorks Account - Edit Profile - Edit community information. The only thing I can do now is do update my profile and nothing else, I don't get anywehre else’

Actually, you do. The message window opens below your profile informaiton with the text of the message. You can then post your own reply to it in that window, and post it to the Newsgroup.

You have to scroll down the page to see it, but it’s there.

Very strange. I do not get any "MathWorks Account - Edit Profile - Edit community information" anywhere. I do not even get "edit" text anywhere on the screen, not any of my profile info either. To show you, this is what I see when I click Reply to this message:

I typically delete all the text initially in the message box once I've typed in my response. Then I post it.

I'd like a screenshot of what Star or Fabi sees, because it's obviously different than mine. Perhaps Fabi asked for an email when replies are made, but did not complete his profile to add an email - just a guess.

[Star Strider]

When I went back and did it just now, mine looks like the one you posted.

I did get something strange earlier, with the message text window visible if I scrolled down.

I get to this page....

I already updated and changed something, but nothing helps

It worked a few days ago, but since today I always get to this website

So you went ahead and filled out the form and it still brings up a blank form? I'd call them on Monday about that. My guess is that it might need your email if you said you want to be updated, and since you didn't have it, it throws you into this screen. But since you say you updated it, but it's clearly not updating, then you'll need to talk with the Mathworks about it.

I have an email address and an organisation filled out. I just cleared it for the example because I thought it's not necessary to show.

Thanks for the effort!

The mathworks.com web page - their home page - does not have message you can reply to on it. So I think you were doing something wrong. So exactly what page were you on, and what link did you click on?

That's not what happens to me when I click "Reply to this message" for that newsgroup message. I get a reply page. I wouldn't use the newsgroup anyway. I'd use Answers here. It has the advantage that you can attach code, pictures, and other kinds of files.

[Fabi Boro]

strange, but thanks for the advise. Should I just post this question at "Answers" again?

[Star Strider]

Alan Weiss seems to have given you a comprehensive reply. If you did what he suggested and you continue to have problems, post here, quote that thread (with URL), and ask for specific additional information. Explain what you did since your original post, include (or attach) your code and other files as necessary, and describe what you still need help with.

Alan and others with applicable expertise in that area will likely reply if you state your question clearly and provide all necessary information.

This is my original question: https://de.mathworks.com/matlabcentral/newsreader/view_thread/345134

I worked through all the documentations suggested bei Alan Weiss. This is how far I got:

    function [xsolve,fval] =  runnested(x0,X,t,Z,Y_corr,lb,ub) 
[xsolve,fval] = lsqnonlin(@nestedfun,x0);
% Nested function that computes the objective function  
    function Y = nestedfun(xsolve)
    Y_theo = (X.^2.*(xsolve(2) - t)./(xsolve(2)-Z).*(1 + xsolve(1).*(xsolve(2)-t))/(1 + xsolve(1).*(xsolve(2)-Z))).^0.5   
        Y = Y_theo(3) - Y_corr
    end
  end

x0 = [-10000 200] start point

xsolve = [a b] my control variables in one variable

-10.000 ≤ a ≥ 10.000

200 ≤ b ≥ 400

lb = [-10000 200] lower bound of xsolve

ub = [10000 400] upper bound of xsolve

X, Z are vectors with data

t is a constant

Y_corr are the values I want Y_theo to be optimized to

Following this documentation:

http://de.mathworks.com/help/optim/ug/example-linear-programming.html

xsolve = ['a' 'b'] is a cell now

I couldn't figure out how to set up the linear programming to assign the lower/upper bounds to my variables. a and b are independently of each other.

Running through the code it gives me that:

Y_theo =

           0         0    2.2134         0         0         0         0         0         0

           0         0    2.4936         0         0         0         0         0         0
           0         0    2.6801         0         0         0         0         0         0
           0         0    2.2166         0         0         0         0         0         0

Y =

     -2.2339
     -2.5204
     -2.7078
     -2.2349
     -2.5188
     -2.7075
     -2.2374
     -2.5182
     -2.7077

Initial point is a local minimum.

Optimization completed because the size of the gradient at the initial point 
is less than the default value of the optimality tolerance.

xsolve =

        -10000         200

fval =

     56.0237

Where are the mistakes? I have a hard time to transfer the documentations to my specific problem
