Dear Walter,

Respectfully, while you may offer some great advice on occasion, I beg your pardon. You need to go shove your spam comment about my serious post up your's. This forum does not belong to you, nor does it make you important, nor can you go around harassing people about their posts.

As for your comment about it being a weekend post and thus low expectations should be the norm, I think it absurd! Have you ever counted how many posts go onto the forum on a weekend? There have been over 140 since Saturday morning and over 240 since Friday morning.

As for John's comment, I stand by the fact that it was woefully vague and inadequate. 1st he says that it is possible but that it will require work...uh...wow, thanks captain obvious. 2nd, he provides another suggestion to create jacobians for all the parameters...uh...thanks again...I actually said that I wanted to apply user defined Jacobians... another point for captain obvious. 3rd, he points me to his optim:tips and tricks, (which I might add hasn't been updated in over 3 years, despite several posts and emails about errors) and yet he doesn't provide any specifics about where to look. Not that I would particularly want to look at something that hasn't been updated in >3 years. In closing, I believe I posted some specific questions or concerns, of which none were addressed.

So, the moral: if your going to try and help, don't do a half a** job at it, or your going to get comments about woeful inadequacy. I never implied that John didn't have a life, but I do take much offense at the induction that I don't. So go shove it again!

As for TMW being interested, I would hope that you are not so naive as to think that they don't peruse this forum, as volunteers and as a source of R&D.

So, walter, my message to you is to stop hating! This is supposed to be a serious question and a community forum, not run by bullies like you.

Compare that with the volume for the average weekday and you'll see that's
relatively light traffic for CSSM.

I can't speak for John, but his message was posted on a Saturday afternoon,
and at least here in Natick it was a pretty nice afternoon. Perhaps John
dashed off his message as a quick response before heading out to enjoy it.

John _volunteers_ his time and experience here. He can give whatever help
he sees fit to whomever he sees fit; if you require him to give you specific
advice, I imagine he may be open to doing a bit of consulting work.

But just a quick bit of advice? In general, people tend to be more willing
to help those people they like. Posting messages like this telling a
well-known and respected member of the community to "shove it again"?
Probably not helping your likeability.

If you're going to reply, I ask you to please do something first. Write
your response, walk away and do something else for 5 minutes, then come back
and reread it as though someone else were sending it to you. Also please
contemplate the fact that not all messages that are written for this
newsgroup necessarily need to get posted to the newsgroup -- on more than
one occasion I've written messages that I then delete unsent after a reread.


Now, going back to your original question about this technical solution
document:

http://www.mathworks.com/support/solutions/en/data/1-18E03/index.html?product=OP&solution=1-18E03

If you have a question about it, or a suggestion for a way it can be
improved or enhanced, please use the link that reads "Please provide
feedback to help us improve this Solution" at the bottom of the page. That
will allow you to provide feedback directly to the technical support staff
responsible for maintaining that document, so that they can incorporate it
into that document.

Whoaa, it's tough way to acknowledge someone who actually even read READ your post. John answer is not completed but he might just go outside and enjoy a sunny day as Steve pointed out. After people who helps here are all volunteers.

I have also few knowledge to be able to chim-in on this kind of sensitivity analysis and linear separable problems, and I could even point to you a good PhD thesis in the 80s exclusive on this topic. I have not yet replied in this post because your request is very vague (we don't what you want to improve and what you have tried). John reply is vague but actually in part with the question that has been laid out.

Dear Steven,

Do you think that I sit around and count the volume of traffic on the CSSM?

I don't think John provided any new or helpful information and he was vague. He would have been better off just enjoying the saturday afternoon, if that was what he was doing, rather than posting a quick but useless response. I don't require any specific advice from him but since he clearly is interested in the topic, he can certainly give it if he so desires. There is no point in just repeating what I stated in my question and being vague though.

I think your advice may be a bit biased...obviously, you side with someone who you claim is "well known and respected", but I ask, well known and respected by whom? Certainly not be me! I don't know this guy and I'm not going to let him call my serious and intellectually challenging post spam! The only reason I was bumping was because there was a lot of spam on the forum. I would hope that TMW wouldn't want "well known and respected" people from discouraging regular, everyday matlab users from posting to the community forum by excessive cheekiness. I've seen it all too often.

It's unfortunate that TMW hasn't already gotten back to the feedback I provided on Friday. Maybe your technical support staff haven't checked their feedback yet... you should let someone know?

But at least he clearly open the door for further discussion. You could for example expose what you have tried, why you are not satisfied with the full Jacobian sensitivity analysis, and explained what exactly you want to improve. Instead of that, your posts turn about "bump, bump and bump". So now the discussion inevitably turns around the "bump" topic.
