MATLAB Newsgroup

The output of the program I'm working on is confusing me. It is supposed to create a table of solutions, and as it finds solutions, it adds to the table, and when no more solutions are found, it displays the table. However, it seems that the code is somehow adding a vector to the table that's not supposed to be there, so that my solutions are "lost" in a sea of numbers. I cannot figure out how it is happening. Here is my code, and my apologies for the length: (I edited out a few things).

starter1 = input('Enter vector of starting guesses in the same format as upper bounds: ');

starter2 = starter1;

options = optimset('MaxFunEvals', 5000, 'MaxIter', 5000, 'Display', 'notify');

number_of_thrusters = input('Enter number of thrusters: ');

if number_of_thrusters == 6

n = 0;

for angle = 0:10:180

disp('Angle:')

disp(angle)

n = n+1;

warning('off','all');

counter = 0;

Coefficients = [Cxwi(n) Cywi(n) Cxywi(n) Cxcur(n) Cycur(n) Cxycur(n) Cxwav(n) Cywav(n) Cxywav(n)];

f = @(x)start_over1(x,Coefficients, x1,x2,x3,x4,x5,x6,y1,y2,y3,y4,y5,y6);

for lb1 = [0 (T1bc+(T1bz/2))]

for lb2 = [0 (T2bc+(T2bz/2))]

for lb3 = [0 (T3bc+(T3bz/2))]

for lb4 = [0 (T4bc+(T3bz/2))]

for ub1 = [(T1bc-(T1bz/2)) 940]

for ub2 = [(T2bc-(T2bz/2)) 940]

for ub3 = [(T3bc-(T3bz/2)) 940]

for ub4 = [(T4bc-(T4bz/2)) 940]

l = [0 0 0 0 0 0 lb1 lb2 lb3 lb4 0 0 0];

u = [940 940 940 940 940 940 ub1 ub2 ub3 ub4 2*pi 2*pi 200];

LB1 = [0 (T1bc+(T1bz/2))];

LB2 = [0 (T2bc+(T2bz/2))];

LB3 = [0 (T3bc+(T3bz/2))];

LB4 = [0 (T4bc+(T3bz/2))];

UB1 = [(T1bc-(T1bz/2)) 2*pi];

UB2 = [(T2bc-(T2bz/2)) 2*pi];

UB3 = [(T3bc-(T3bz/2)) 2*pi];

UB4 = [(T4bc-(T4bz/2)) 2*pi];

sn1 = fmincon(@myfun1,starter1,[],[],[],[],l,u,f, options);

if (sn1(7)>=LB1(1) && (sn1(7)<= UB1(1) || sn1(7)>=LB1(2)) && sn1(7)<=UB1(2))...

&& (sn1(8)>=LB2(1) && (sn1(8)<= UB2(1) || sn1(8)>=LB2(2)) && sn1(8)

counter = counter + 1;

solutions_table(counter,:) = sn1;

end

sn2 = fmincon(@myfun1,starter2,[],[],[],[],l,u,f, options);

if (sn2(7)>=LB1(1) && (sn2(7)<=UB1(1) || sn2(7)>=LB1(2)) && sn2(7)<=UB1(2))...

&& (sn2(8)>=LB2(1) && (sn2(8)<=UB2(1) || sn2(8)>=LB2(2)) && sn2(8)

counter = counter + 1;

solutions_table(counter,:) = sn2;

end

end

end

end

end

end

end

end

end

disp(solutions_table)

end

Now, what seems to be happening is that my "starter1" is somehow becoming a part of solutions_table. If anyone can point out what's going on it would be MUCH appreciated!!

I meant to add a sample of the output. Here is a sample of columns 9-13. As one can see, the solutions are interspersed with the initial guess for some reason.

Apply TodayThe newsgroups are a worldwide forum that is open to everyone. Newsgroups are used to discuss a huge range of topics, make announcements, and trade files.

Discussions are threaded, or grouped in a way that allows you to read a posted message and all of its replies in chronological order. This makes it easy to follow the thread of the conversation, and to see what’s already been said before you post your own reply or make a new posting.

Newsgroup content is distributed by servers hosted by various organizations on the Internet. Messages are exchanged and managed using open-standard protocols. No single entity “owns” the newsgroups.

There are thousands of newsgroups, each addressing a single topic or area of interest. The MATLAB Central Newsreader posts and displays messages in the comp.soft-sys.matlab newsgroup.

**MATLAB Central**

You can use the integrated newsreader at the MATLAB Central website to read and post messages in this newsgroup. MATLAB Central is hosted by MathWorks.

Messages posted through the MATLAB Central Newsreader are seen by everyone using the newsgroups, regardless of how they access the newsgroups. There are several advantages to using MATLAB Central.

**One Account**

Your MATLAB Central account is tied to your MathWorks Account for easy access.

**Use the Email Address of Your Choice**

The MATLAB Central Newsreader allows you to define an alternative email address as your posting address, avoiding clutter in your primary mailbox and reducing spam.

**Spam Control**

Most newsgroup spam is filtered out by the MATLAB Central Newsreader.

**Tagging**

Messages can be tagged with a relevant label by any signed-in user. Tags can be used as keywords to find particular files of interest, or as a way to categorize your bookmarked postings. You may choose to allow others to view your tags, and you can view or search others’ tags as well as those of the community at large. Tagging provides a way to see both the big trends and the smaller, more obscure ideas and applications.

**Watch lists**

Setting up watch lists allows you to be notified of updates made to postings selected by author, thread, or any search variable. Your watch list notifications can be sent by email (daily digest or immediate), displayed in My Newsreader, or sent via RSS feed.
