How come Matlab returns 6 when asking for the rank of an identity matrix of size 7?
rank(eye(7))
apparently there has to be more text here for me to be able to post the question.
Thanks
rank in matlab 2014a uses svd, not svds. If your local file uses svds the installation is corrupted. I recommend to reinstall Matlab and set write restrictions to the toolbox folder afterwards to prevent such problems happen again.

I find several solvers appeared in MiniZinc Configuration. So what is the advantage of each solver? And what problems are classic examples for each soler? Thanks. solvers in MiniZinc Configuration
All MiniZinc solvers known to the MiniZinc team, including those in the bundle, are described on the software page of the MiniZinc website. Look for the heading "FlatZinc implementations".
Note that most of these solvers are full solving environment and that not all features of a solver might be natively available in the MiniZinc environment.

As you can see above those are the only buttons I see. There is no preview to see how the report looks like. I'm not sure if I installed everything perfectly but I just added jasperreports-6.2.0 in the libraries and iReport-5.5.0-plugin. My NetBeans version is 8.0.2
Alright, I solved it. I downloaded the plug-in here instead http://sourceforge.net/projects/ireport/files/iReport%20Plugin%20for%20NetBeans/iReport-5.6.0/iReport-5.6.0-plugin.zip/download?use_mirror=nchc

I am trying to run a MATLAB program on my computer running Ubuntu 12.04. Then when it runs to the code
load('data\sparse_combinations\Tw.mat', 'Tw')
MATLAB will report this error
Error using load
Unable to read file 'data\sparse_combinations\Tw.mat': no sucn file or directory
But when I enter the directory 'sparse_combinations', then run the code
load('Tw.mat')
it works well.
Can you help me find the reason?
As pointed out by #Marcin the problem is the usage of the wrong path seperator.
A good and general fix for this type of issue would be the use of fullfile - this command takes care of the issues of path seperation and platforms for you.
load( fullfile('data','sparse_combinations','Tw.mat'), 'Tw')
will work both on windows machines as well as Linux/Unix ones. No need to change code when porting to other platforms!

To all MATLAB and Simulink users
I am new in matlab and simulink. I calculated a motion with time in matlab and then I would like to use it as a input data in simulink. Anyone can teach me how to do this please. Please tell more details (which block and how to set both in M and S) as I am a really really new user.
Thanks.
the block you are looking for is called From Workspace. The easiest way to import data with it is maybe as a time series. Try using your data, and read this for trouble shooting.
