Having issues installing Imaging Processing Toolbox
I have a student license in which Imaging Prossessing Toolbox is included, but when I try to install the image processing toolbox, it never installs and the loading circle goes on for hours. I had it trying to install for 8 hours and nothing happened.

Matlab extremely slow to start up due to error mwdocsearch.exe
Matlab 2022B has a bug in "mwdocsearch.exe" which is automatically run when launching Matlab and results in the following error.
Caught "std::exception" Exception message is:

I tried to upgrade to 2023a and same bug occurs.
Does anybody know how to cure this failure or disable the "mwdocsearch.exe" from running?

How to solve PDEs with only one side boundary conditions?
Hi,
I met some problem in solving a system of PDEs with only the left-side boundary conditions. I will revise the built-in example Solve System of PDEs a little bit to show the problem:
Everything is identical to the example Solve System of PDEs , except the two boundary conditions in the red rectangle, which are at the left hand side (x=0), rather than the right hand side (x=1).
So my question is, can I solve the PDEs through PDEPE (I guess not because it needs BCs on both sides)? Can I use matlab PDE toolbox, or other method, to solve the equations?
I really appreciate your help. Thanks!

Video frames all garbled and not in sequence
Hi
I am using imaqtools in particular using gentl driver with Lucid vision camera. Ni Max and Arena records a sequence of frames just fine.
But matlab is having trouble. Initially the frames are in sequence for first few ten frames and then the frames randomly start jumping around e.g., frame 260 appears prior to frame 259 etc.
When I look at frame time, it all seems to be in sequence. Here is my code
Not only that the timing shows that frame interval is about 40ms.

colormap using command line in implay()

So my images are grayscale uint16
implay sets it as gray(256)
From the pull down menu I change the settings to manually select 0-2000 or whatever other than 255.
Otherwise all the images are dark.

When is subsystem reference a better choice than model reference?
I am trying to understand the difference between "model reference" and "subsystem reference". I came across this documentation page, but no matter how many use-cases I reviewed, I never seem to end up with a "subsystem reference". From the flow chart shown in that page, the only way conclude with "subsystem reference" is when the block does not have a defined interface, or is not re-used or does not change. These are the antithesis of arguments for any creating any type of subsystems. Can someone comment on practical situations when a "subsystem reference" will be useful over "model reference"? Are there computational costs associated with "model reference"? I am inclined to believe that in practical cases in the industry, "subsystem references" are rarely used.I am trying to understand the difference between "model reference" and "subsystem reference".

How to combine panes, or how to redock an undocked file in main editor pane
When I am editing multiple files, I have them all open in one undocked editor window, each one with it’s own tab.
Sometimes I like to rearrange them by dragging the tabs. It’s very sensitive to vertical movements (that’s a bug too, it should not be so sensitive in the vertical direction) so if I move a little bit vertically, the editor creates a separate pane for the tab. I can’t figure out how to move it back to the pane with all my other files. I can undock, then dock all in editor, but the editor just puts it back into its separate pane.

Can I attach multiple DBC files to a single “canChannel” object?
I am using the Vehicle Network Toolbox, and would like to either concatenate two DBC files or attach multiple DBC files to the same "canChannel" object.

Example of a Device Driver integrated in Simulink using a Custom block
Hi,
Can someone point to any example/sample code demonstrating integration of a board specific device driver code ( for example read data from a serial bus like CAN/SPI, or even simpler read data from ADC etc.. ) into SIMULINK with a custom block.
Which is a better choice for such a requirement , S-Function block or a C Function block?
I want to possibly simulate and also generate the glue code to integrate with the low level driver with the embedded coder.
Thanks in advance
