I followed the steps how this post says. I put the log4j.jar into classpath.txt and it appeared on the list of .jar files when I executed javaclasspath. After that I called (e.g. javax.log4j.Logger) or (e.g. import(’javax.log4j.*’), Logger ) but it didn’t work.

So if you could help me I’d appreciate it. If I manage to develop an interesting application including log4j API, I don’t mind to share with everyone.

Kind Regards,
Jose Miguel

There isn’t currently any way to move the docking controls. Feel free to submit an enhancement request.

The function browser provides a sort of hybrid approach to navigating the doc that combines the categorical listing with search capabilities. That is, the search results include relevant categories, and you can browse through those categories within the search results listing.

In your example, you might open the Function Browser and type “eigenvalue” into the Function Browser’s search field. This matches one category, “Eigenvalues and Singular Values”, which allows you to bypass the three levels under which that category is nested and jump straight into that category. It also matches a list of individual functions and shows those functions’ summary lines. This list does include eig, so if you want to avoid the categorical listing altogether you can.

It sounds like you are also having some difficulty with the function browser’s user interface. The page that you see is a trimmed down version of the function reference page that focuses on the function’s syntax, since this is most likely to be the user’s biggest need while working in the Editor or Command Window. It shouldn’t disappear just because you move your mouse, unless you move the mouse over another entry in the function browser without moving it towards the reference page window. I know that the function browser’s development team put a lot of work into understanding users’ mouse gestures and doing the appropriate thing, so if you’re finding that the behavior isn’t completely optimal I’m sure they would like to hear about why it doesn’t work for you. If you need the reference page around for longer than just a quick look you can “tear it off” of the function browser using the “grip” at the top of the page. This will allow the page to stick around, floating above the editor or command window, until you dismiss it. Or, if you need more detailed information, the “More Help” link will open the full function reference page in the Help on Selection window. I know that you mentioned that you don’t necessarily like that window. If you’d rather have that link open the Help browser, you can change that behavior in the Help preferences (Type “preferences Help” in the Command Window).

As we mentioned above, feedback on how users actually use our tools is incredibly useful to us. I hope my comments above have been helpful, but if you have more feedback or need any more information don’t hesitate to get in touch with us again.

So, lets say that I want some information on the eig function. So, I guess that it is under Mathematics & then Arrays and Matrices. Oh, there are 5 more sub-levels. Maybe under Elementary Matrices. No. Maybe under Array Operations. No. Array Manipulation. Maybe I’m at the wrong level. Let’s see, there is Data Analysis. Oops, I think I went up too many levels. Oh, there is Linear Algebra. Oh, it must be there under Eigenvalues etc. Yep, there it is, the eig function.

So, after ~2 dozen meandering clicks, I finally am confident that if I click on eig, I’ll get what I’m looking for. So, I click and a nice attractive window pops up . . . and disappears! Where did it go!? Oh, I see, if I freeze and don’t move my mouse at all, it stays up. It appears to be the FRP for eig, but its like I’m looking at it thru a paper towel tube. No way I can hop back to the Editor to my .m file and type a few characters and glance over to the reference.

You say you got favorable input from usability testing with this? Please, teach me how this can be useful. What is so different about my work flow relative to those who like this?

Not only does this require that the user has a mastery of the indexing scheme for the function topics, but it also requires the user to have an almost photographic memory so you can glance at the fragment of the FRP that he can see while he returns to editing. I’ve been using MatLab for ~40 hours a week for 6 years now & frankly, I gave up on trying to remember the function indexing scheme ~4 years ago. That is why I focus on the alphabetical list. Never more than 4 clicks & I’m reading the FRP.

I know this indexing of a menu has been a challenge for software writers for a couple decades now and it gets more difficult when the total number of menu options exceeds 50 to 100. Think how much more difficult it is in the world of MatLab where just MatLab alone has over 2800 functions!

I see your challenge. And, I recognize that you do need a topical index as well as the alphabetical index. But, since the total number of functions is so large, you really need to make it easy to use some other way to get to the FRP. I gave up and use the alphabetical listing. But, I see that disadvantage since the user must have a good guess about the function’s name.
