How to connect a Basler camera to MATLAB
Hi everyone,
I have a Basler acA1920-155um that I am trying to connect to MATLAB using USB 3.0. This has proven more difficult than anticipated.
I’ve followed this (outdated) guide:
https://www2.baslerweb.com/media/downloads/documents/application_notes/AW00134303000_Application_Note_Basler_pylon_GenTL_Producers_with_….pdf
My understanding of what should happen is this:
1. Install the current version of the Basler Pylon Software Suite
2. Install the Image Acquisition toolbox
3. Download the GenTL support package via MATLAB
and….it should work. I open the image acquisition app in MATLAB and it does not find any cameras. I checked using imacqhwinfo and it does show that the GenTL diver is present, but no devices.
What I’ve tried:
I’ve attempted to download the Pylon SDK, and the GenTL drivers to replace them, to no avail.
The camera runs fine in Basler Pylon Viewer so I know it’s not a physical connection problem.
Any guidance is appreciated.Hi everyone,

HDL Coder Error when converting AXI4 interface with different data rates
I’m having trouble understanding this error from HDL coder:
Failed All the DUT ports connecting to the "f2h_sdram0 Read" interface must be running at the fastest rate in the generated DUT HDL code. Port "data_in" uses sample rate of 5e-06, the fastest rate in the DUT HDL code is 2e-07.

I want to read from a particular address in memory every 5 us. I don’t want to read every 2e-7 seconds and flood the bus with uneeded read requests. I tried checking the timing legend and nothing even seems to be running at 2e-07 so i’m not sure where it is getting that rate from in the first place.
Am i approaching the sampling logic for this incorrectly? Instead of controlling when it performs a read by changing the execution time of the read-slave-to-master interface and Data signals, should i let the execution time be set to -1 (inherited) and control the read time by changing the rd_dvalid signal using temporal logic in my stateflow chart?

Impossible to install the latest version of Matlab Connector on a Linux computer
I have installed the latest version of 2025b on a Linux system with Ubuntu 24.04.2 LTS.
It is not possible to install the Matlab connector (2025.11.0.2). The process is terminated and the following error is thrown:
Gtk-Message: 11:08:08.425: Failed to load module "gail"
Gtk-Message: 11:08:08.425: Failed to load module "atk-bridge"
I have never had any issues with the Connector whatsoever in the past. Following suggestions from the helpdesk, I did several things already: installing from a different folder, bypassing the firewall, disabling the router, install but not as superuser, fresh Matlab install, etc. It seems the installer completes extraction but fails to start services.
I am very much dependent on the Connector and it is very frustrating that 2025b & Connector do not work out-of-the-box. Furthermore, the process of troubleshooting has become beyond my expertise.

Simulink model freezes at 8% during compilation showing “updating library links blocks: started” in MATLAB 2024a
I am using MATLAB R2024a on Windows, and I am experiencing a consistent issue with one specific Simulink model. During simulation or code generation, the process freezes at 8% during compilation, showing the message “Updating library links blocks: started” in the lower left corner of the window. It remains stuck indefinitely at that stage.
Even if I try to cancel the build, MATLAB becomes unresponsive and eventually crashes, requiring a full restart. This happens almost every day, usually when reopening or restarting the model.
As a temporary workaround, I have been deleting the slprj folder and the .autosave file, and then running the command clear classes. After that, the model compiles normally again — but the issue reappears later.
This model uses several toolboxes, including:
Aerospace Blockset
Aerospace Toolbox
UAV Toolbox
Simulink, Simulink Coder, MATLAB core toolboxes.
The model does not use model references or custom libraries.

Orifice (TL) temperature-dependent parameterization
Hello together,
I would like to specify an oil filter in Simscape. At the moment, I use the TL-Library orifice component for this task. I have test data available to specify the volumetric flow rate depending on the fluid temperature and the pressure drop. Unfortunately, I can’t find any option to make the orifice behave temperature-dependent. There is only an option to parameterize the volumetric flow rate vs. the pressure drop. If I do so, the model behaves the same for each temperature.
Does anybody know how I could model this component in an accurate way?

Error trying to get started with get_chanlocs plugin for EEGLAB “Unrecognized function or variable ‘placeFiducials'”
Hello,
I am very new to MATLAB, so apologies in advance if this is a trivial question. My university has recently acquired a Structure Sensor 3 scanner, and we would like to use the 3D models to conduct source localisation. It looks like get_chanlocs is the perfect tool to get the locations of the channels on the 3D models, but I am running into issues when trying to open the models in EEGLAB.
After importing my EEG data (.bdf file, from a Biosemi system, 64 channels), I use the "Locate electrodes in a 3D head image" option. First, I am prompted to select my 3D model, where I choose the .obj file created with the 3D scanner. Then I am asked if I want to use a template; since I do not have one yet, I select "No, I will select locations in order". At this point, MATLAB gives me this error:
Unrecognized function or variable ‘placeFiducials’.
Error in get_chanlocs (line 177)
fiducials = placeFiducials(head_surface);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I think it means there is a function (placeFiducials) that the script is trying to use, but cannot find. But I am not sure where this function should be located. Am I missing a plugin, or could this be an issue with version compatibility?
I am currently using:
– MATLAB R2025b
– EEGLAB 2025.1.0
– FieldTrip 20250106
Installed EEGLAB plugins:
– Biosig v3.8.4
– ERPLAB v12.10
– clean_rawdata v2.11
– ICLabel v1.7
– firfilt v2.8
– dipfit v5.6
– EEG-BIDS v10.3
– get_chanlocs v4
– NFT v2.2
Thanks in advance if anyone can help me with this.Hello,
