tcpclient objects are not supported by icdevice. Hardware interface object must be a serial, tcpip, visa, or gpib object.
I was using tcpip interface object with my matlab interface intrument driver. But, it was giving warining that tcpip will be removed in future release. So, to make my code work even in future I changed tcpip with tcpclient as suggested. But, it is not supported by icdevice. So how can I use my interface intrument driver with functions that are not going to be removed in near future. Also, can anyone suggest when this tcpip function will be removed fro Matlab? Please find below code snippet which is giving error. "tcpclient objects are not supported by icdevice. Hardware interface object must be a serial, tcpip, visa, or gpib object."

Different ways of joining empty strings produce different results
Here are different ways to join empty strings. One may expect the results to be the same, but in reality, they give 3 different kind of answers. What is the rationale behind it?
join00 = join(string.empty(0,0), "/"); % 0x1 string
join01 = join(string.empty(0,1), "/"); % <missing>
join10 = join(string.empty(1,0), "/"); % <missing>
strjoin00 = strjoin(string.empty(0,0), "/"); % ""
strjoin10 = strjoin(string.empty(1,0), "/"); % ""
strjoin01 = strjoin(string.empty(0,1), "/"); % ""
Background
In my application, multiple series of strings are joined. Sometimes though, certain series is empty, in which case I am tasked to detect those results and replace them with "N/A". Through trial and error, I found that I cannot simply detect those results with only isempty(result), ismissing(result), or (isstring(result) || ischar(result)) && strlength(result) == 0, but I need the combination of all of them, which makes me wonder if there is any reason behind the different behavior.Here are different ways to join empty strings.

How do I create “Junction ID” & “Road ID” in RoadRunner?

ROS rate in Simulink with standalone code generation
Hi everyone,
the following problem I have: I built a simulink model to generate a standalone ros node. It is a simple controller. I would like to publish the data with 10 hz, so I defined the sample time (by the blank message) 0.1.
After building the model and running the ROS-node, I test the publisher frequency with
rostopic hz ….
and I get 9.94, 9.95….
If I implement the same functionality in Python ROS-node, I get the desired 10 hz, so it must be some code generation issue and not the limitation of the target hardware.
Could you help me, how to have a more stable publishing rate in a generated Simulink ROS-node?

Simulink External Mode not working for TI F280049C “Error occurred while executing External Mode MEX-file ‘ext_comm'”
I am currently trying to run a simulation via simulink but I am having trouble getting the monitor and tune to work, when simulate I get this error Error occurred while executing External Mode MEX-file ‘ext_comm’: Failed to connect to the target. A time-out occurred while waiting for the connection response from the target. Possible reasons for the time-out: a) The target is not switched on. b) The target is not connected to your host machine. c) The application for the model is not running on the target. You might have clicked the Stop button. If the Run button is not dimmed, click it. Otherwise, click the Build button, which downloads and runs your application on the target.
The program is able to build but and load onto the board but getting it to run via monitor and tune does not work
So far I have tried
Changing the UART serial port in hardware implementation to the port other than the Auxiallary port
Changing the OSCCART frequency from 20MHZ to 10Mhz (also tried 25MHz)
Uninstalling and reinstalling the XDS110 drivers
Closed CCS
Changed SCI_A to alternate ports
whats funny is that when i changed the UART ports yesterday it technically "ran" as in it said it was running and didnt give any errors, but the simulation stayed at T=0.00 no matter how long i left it running. but now today it just doesnt work period.
I will include a bunch of relevant screenshots, i also followed this post which had similar issues already but nothing works still

Use Vehicle Network Toolbox with multiple CAN databases on a single CAN bus
I’m using Vehicle Network Toolbox (VNT) to itneract with a CAN bus using database files (.dbc files). I’ve got it working with the code below.
chanA = canChannel(‘Kvaser’, ‘Leaf Light v2 1’, 1);
chanA.Database = canDatabase(‘OperatorControl.dbc’);
That works fine, but now I want to interact with messages that are defined in different databases, but are on the same CAN bus. What is the best way to do that? Should I define a new CAN channel? I could do that, but it seems like it would become cumbersome if there are a lot of extra channels to deal with.
Can I combine multiple CAN databases into a single one before adding it to the CAN channel? Can I add more than one database to the CAN channel? I haven’t been able to find a way to do that.

Webcam with App Designer
Hi everyone!
I have an app that I have created in app designer in which I use the use of the web camera … when I want to do packaging it marks an error and loads me the following files:
Utility.p

how to use GPU to run idNeuralStateSpace
Hi everyone,
I am trying to use Neural state space model to identify the state derivatives using only measurement data. The system that I use requires small sampling time which leads to the requirement of large training data. I want to use GPU while estimating nonlinear state-space model using the built-in function nlssest and idNeuralStateSpace. Do you mind letting me know how I can utilize the GPU while running the model?

agrupacion de datos de una tabla
Holas,
tengo una tabla ‘tData’ de tamano: 152709×14, que resume senal de varias variables de un instrumento de medicion (FTIR) y quisiera disminuir el ruido agrupando los valores de la senial en grupos de a 10 es decir obtener una nueva tabla ‘tDataReduced’ de un tamano 15270×14. la tabla tData cuenta con una columna de texto con el nombre de cada serie de medicion llamada ‘MeasID’, una columna de fecha y hora llamada ‘Time’ y 12 columnas con valores numericos.
Para este proposito, Estoy usando este codigo:
% (1) Crear un vector de índices para agrupar las filas en grupos de 10
indices = repelem(1:ceil(height(tData)/10), 10, 1);
indices = indices(1:height(tData));
% (2) Calcular el promedio de cada grupo de 10 filas
tDataReduced = grpstats(tData, indices, ‘mean’);
% (3) Eliminar la columna de índices generada por grpstats
tDataReduced(:, ‘GroupCount’) = [];
%%%%%%%%%%%%%%%%%%%5
Pero se tranca en el paso (2) indicando este error:
%*****************
Index exceeds the number of array elements. Index must not exceed 14.
Error in dsgrpstats (line 97)
[group,glabel,groupname] = mgrp2idx(a_data(groupvars),a_nobs);
