@Rajkiran - I don’t know what to suggest. Check that you named your file “slblocks.m”, that is is on the path, (which -all slblocks.m) and that it returns a valid blkStruct structure. Good luck!

Hi Seth,

Thank you for much for the great tutorial.
I am using MATLAB R2007a, and I have successfully added my own library to the Simulink Library Browser although there is a small problem, which I have to run the M-file stored in my library folder. Thank you so much

Regards,

Kevin

@Graham - That is not something I have encountered before. Please work with technical support to investigate this problem further.

Hi Seth,

I’m using a custom library in Simulink 2008a on Windows. It has some hierarchy, so it contains some sub-libraries with different numbers of blocks in them.

I find that switching between sub-libraries is slow, particularly for those with a lot of blocks. One contains 40 blocks and takes 10-12 seconds to load, and this doesn’t improve once it has already been loaded. I’m not talking about opening the library browser, I’m talking about moving back and forth between sub-libraries.

The same library in 2007b switches between sub-libraries very quickly - there is hardly any noticeable delay.

Is there anything I can do to improve this?

Regards,
Graham

Hi Jeremy,

Insert Rate Transition Blocks in each of the R,G,B color lines before feeding them to the To Multimedia File block. In each of those rate transition blocks set the output sample time to 1/30 (which is the rate of the input video). This should work.

Hi Seth,

I have been looking at SimEvents modelling with the Image processing blocksets. I want to record the output video of the “Video Streaming Over Bandwidth-Limited Communication Channel” demo, however I cannot write the data directly from the video viewer to a multimedia file as I get a invalid sample time error. I run out of memory if I try to write to workspace with a large number of frames. Is there a better way of doing it?

Thanks Jeremy

Will it take another 9 years to release a documented and supported uitree/uitreenode widget that can be used to build tree browsers for other applications without the risk of using an unsupported feature?

It didn’t! It took one year. It took nine years before it got scheduled.

Did it really take 10 years to get the library browser on unix? Wow!
