Error configuring Arduino Uno R4 Minima in MATLAB 2024b
I’m encountering an error when trying to set up my Arduino Uno R4 Minima in MATLAB 2024b. After connecting the device to my computer and selecting the board in the "Hardware Setup" section, I receive the following error:

Error: Phasor block is not allowed with the Continuous or Discrete simulation method
Hi,
I am simulating a microgrid which consists of a synchronous machine (which models a diesel generator), wind turbine and load. The wind turbine model requires a phasor simulation type (in the configuration parameter of the powergui). However, the rest of models require a discrete simulation type. Running the simulation for the microgrid model using a discrete simulation type gave the error:
The ‘microgridModel_DG_WT_Load/Wind Subsystem/B25_WF Bus Data acquisition/Sequence Analyzer (Phasor Type)’ Phasor block is not allowed with the Continuous or Discrete simulation method.
May I know how do I go about solving this problem? Any help or advice would really be greatly appreciated!Hi,

Value Function Iteration Code Not Converging
Hello all, I am currently coding a value/policy function iteration code to solve an economic problem. The problem that this is solving for is that there is a certain amount of S and R currently owned (these are the state variables). S and R generate income, which must be allocated to purchase more S and R for the next "round" (S’ and R’, equivalently. S’ and R’ are the control variables). This code solves for the optimal amount of income that should be spent on R’ at any given level of S and R. Right now my code below only works at specific parameter values and does not converge–the error term gets stuck, and I cannot seem to figure out why. My code is below. Any help on what could possibly prevent it from converging would be greatly appreciated. Thank you all in advance!

Why does containers.Map(‘KeyType’,’double’) silently return a map with KeyType ‘char’ ?
I would have expected an error if the second argument is strictly required. Giving me a wrong map just pushes the error to runtime when I call it with an ‘double’ key.

deepNetworkDesigner: autoscrolling, connection preservation, undoing, and landscaping
I am encountering several issues with deepNetworkDesigner.
(1) I have a large network whose layers do not fit entirely on one screen, or at least not at a magnification level that allows me to easily see, distinguish, and manipulate the layers. How do I connect one layer to a second layer that is off-screen? When I try to drag a connection wire toward the destination layer, the pane does not autoscroll to let me reach it.
(2) I have one layer A that fans out to many output layers C1,C2,…,CN. I now wish to replace A with a different layer. Is there a way to do that, without having to tediously and manually reconnect the N outputs? Similarly, what if I wish to insert a layer B, so that A now feeds only to B but it is B that fans out to C1,C2,C3,…CN. Again, can this be done without breaking all N connections and having to manually redraw them?
(3) Is there a way to undo a change to a network (something like Ctrl-Z)?
(4) Is there a way to reorient the pane so the network flows left to right, instead of top to bottom (something like a landscape mode, rather than portrait).I am encountering several issues with deepNetworkDesigner.

Why does my system object get an assertion failure error
Hello all
I am kinda new in MATLAB/Simulink，and learning the multi-object tracking task based on simulink by Track Closely Spaced Targets Under Ambiguity in Simulink. I want to finish image tracking task. I already have the target detection result based on YOLO. When I was writing based on the HelperDataLogReader class in the example, an assertion failure occurred. But I have looked up a lot of relevant materials but can’t solve it, and I hope someone can help me. Here is my code and the target detection result of YOLO, thank you so much！

endHello all
I am kinda new in MATLAB/Simulink，and learning the multi-object tracking task based on simulink by Track Closely Spaced Targets Under Ambiguity in Simulink. I want to finish image tracking task. I already have the target detection result based on YOLO. When I was writing based on the HelperDataLogReader class in the example, an assertion failure occurred. But I have looked up a lot of relevant materials but can’t solve it, and I hope someone can help me. Here is my code and the target detection result of YOLO, thank you so much！

How can I improve this line of code perfomance wise?
When using the profiler to look at the performance of a function I need to work with, I saw that one line takes up much time
invalidIndex = any((coords<ddims(1:3)) | (coords>ddims(4:6)),2);
So it just checks if the point contained are within the bounds. The size of coords is nx3
Is there any way this line can be improved perfomance wise. I couldn’t think of anything else…When using the profiler to look at the performance of a function I need to work with, I saw that one line takes up much time

Pose Estimation and Orientation for a UAV in MATLAB
I have the following data:
Ax, Ay, Az (m/s^2) – update rate 10 Hz
Gx, Gy, Gz (rad/s) – update rate 10 Hz
GPS LLA (deg deg meters) – update rate 2 Hz
Roll, Pitch, Yaw (degrees) update rate 10 Hz
I want to develop a GNSS aided INS.
I am following the example given below:
https://www.mathworks.com/help/nav/ug/imu-and-gps-fusion-for-inertial-navigation.html
trajOrient = trajData.Orientation;
I got this using the below code:
%%
clear all;
close all;
clc;
%%
%Load sensor data
load IMUData.mat IMUData;
accelerometerReadings = IMUData(:, 2:4);
gyroscopeReadings = IMUData(:, 5:7);
%% Sampling Rate
imuFs = 10; %Hz
decim = 1;
fuse = imufilter(‘SampleRate’,imuFs,’DecimationFactor’,decim, ‘ReferenceFrame’, ‘ENU’,’AccelerometerNoise’,1e-6, ‘GyroscopeDriftNoise’,1e-6);
%%
OrientationData = fuse(accelerometerReadings,gyroscopeReadings);
trajVel = trajData.Velocity;
How do I get this data?
trajPos = trajData.Position;
How do I get this data?
trajAcc = trajData.Acceleration;
accelerometerReadings = IMUData(:, 2:4);
trajAngVel = trajData.AngularVelocity;
gyroscopeReadings = IMUData(:, 5:7);
Also, I do not have magnetometer. I have to do it using acc-gyro only.
initstate = [1-4 % Orientation as a quaternion
5-7 % Position (NED) %but my frame is in NEU maybe
8-10 % Velocity (NED)
11-13 % Delta Angle Bias (XYZ)
14-16 % Delta Velocity Bias (XYZ)
17-19; % Geomagnetic Field Vector (NED)
20-22] % Magnetometer Bias (XYZ)
