You will get an error if you are using an version of MATLAB older than R2008b. SimMechanics Visualization has been completly redesigned in MATLAB R2008b. The model uses new features available only since R2008b and because of that it is not compatible with earlier versions.

The error is very clear it cannot find the file, probably you executed the MEX command from a different folder ?

Otherwise try "mex -setup" to reset your compiler settings.

03 Nov 2009 Allstats Many statistics of a vector Author: Francisco de Castro Hanselman, Duane

This function calls functions that exist in the Statistics toolbox, but does not make that requirement known. No error checking is done. Help text is ambiguous and no examples are given. The last two help sentences describe unknown concepts that require more than a passing inspection of the function code to understand.

03 Nov 2009 Toward a program development and documentation toolbox ...offering important and structured complements to Edit/debug, & Mlint Author: Nedialko Nedialko

Hello Cristian,
It is a nice surprise to see your note at fileexchange.
I hadn't been around here for a while, so I didn't see it until now.

My idea was to provide a couple of develop/debug tools packaged in a separate toolbox.
Some fairly unsophisticated things are surprisingly still missing even in the latest Matlab releases.

One such thing is matching 'begin' & 'end' blocks of code.
Emacs does it, but ...
a. not everebody uses it
b. it's hard to configure right for the novice

So I developed a Matlab function to do the same - it could be part of, say - I style-checker which goes beyond my ambition, but is no doubrt useful: the world is full of half-literate 'research' code, documented in 'chinese-like' Ingilish ;-)

Another very useful and yet again 'not-a-priority-for-mathworks' tool would be a good call-tree generator. fileexchange has seen a couple of really 'pedestrian' ones, whose output is hardly intelligent and overwhelming in its flow of less useful details.

Would be nice to hear from you, if ever.
Ned.

P.S. I had submitted a toolbox proposal to Mathworks. Then after a long time I got contacted by some female pencil pusher, who said that I had to register a business to be entitled support and further interest from them. So the idea fell right down the stack of my numerous priorities.

Is there a simple way to edit bicoher to normalize it such that it's giving the bounded (0-1) version rather than the current skewness version?

I can't access the Kim and Powers paper and if others have sucessfully done this, I'd love to know how!

03 Nov 2009 Kalman filtering framework Object framework for filtering using Kalman filter, EKF, or UKF. Author: David Ogilvie Kenz

(Excuse me, I wasn't clear. I meant for the "continuous-discrete" functionality, which is where this kind of framework could come in truly handy)

03 Nov 2009 Kalman filtering framework Object framework for filtering using Kalman filter, EKF, or UKF. Author: David Ogilvie Kenz

Interesting idea, but the lack of documentation kills it. Perhaps if the examples had been better chosen, for instance to include multidimensional problems, it might have been clearer. As it were, when I tried a simple spring-mass system I got lots of "matrix dimensions must agree" errors, and, being unfamiliar with Matlab's `classdef` features, couldn't really sort out what was going wrong.

Very nice work thanks a lot. It saves a lot of work !!
However, I have some troubles using the @...@ text.
Could you put a simple example to illustrate the method.
On my side I have the following line:
$x_{\text{ter}}$ @xter@
At the end, the legendbox is still too large. I do not understand where is my mistake. For information, I use the MATLAB Version 7.8.0.347 (R2009a).
Thanks in advance.

03 Nov 2009 Counter. Counter. Hours, minutes and seconds. Author: pablo_zuniga Zúñiga Jos

Here are the first few lines of this script:
%Cronometro.
clc
clear
resp='s';
while (resp=='s')

clc
clear
a=input('Ingrese horas\n\n');
disp(' ')
b=input('Ingrese minutos\n\n');
disp(' ')
c=input('Ingrese segundos\n\n');
disp(' ')

Potential users should be aware that running this script does clear the entire workspace without notice (and it do so twice!), so all your work will be lost.
This script serves no purpose other than being a programming exercise for the author, so why share it here?

Hello Guy,

I intend to build a full car model of active suspension that will be controlled by fuzzy logic in simmechanics, I want to make your model as the basis of my model since your model is pretty great. However, I still confused on some parts. Can you give me any suggestion which parts of your model should I remove? And where I can add the fuzzy controller box.Please give me explanation. Your help is highly appreciated. Thank you.

Regards,

Rendy

03 Nov 2009 Image segmentation using statistical region merging Very simple and fast image segmentation code using statistical region merging. Author: Sylvain Boltz Boltz, Sylvain

Hi,

This algorithm is designed for images with 3 color channels.

for i=1:3
im_final(:,:,i)=image_seg(map+(i-1)*n_pixels);
end

if your image is black and white or has a different number of channels you should change all the hard coded 3 by size_image(3).

if this does not correct the problem, can you send me the image causing problems as well as the way you open it (e.g. image=double(imread(...))).

Thanks for your feedback

02 Nov 2009 Write RGB text over RGB images Utility which renders RGB text over a RGB matrix, allowing you to save the image as file... Author: Davide Di Gloria Omar

This script was very useful for me. Thanks Davide!
Piyush, I worked around the text size by introducing a new argument "rsz" in the function and the following line just before the two last conditionals where the text is blend or overwrite in the target image:

overlay = imresize(overlay,rsz);

Be aware that if you chose a too big resizing factor so that the text is larger than the target image you will end up with a problem. It would be nice if you or someone else include an error handling here.

Thanks again.

Omar
