Hello everyone!

I am trying to plot my results following Temperatures for a Transient Thermal Model on a Square on https://www.mathworks.com/help/pde/ug/pde.steadystatethermalresults.interpolatetemperature.html. However, the only plot that shows is the one at the end of the t array (t = 952), plus an unlabelled one: could anybody please help me understand what I am doing differently?

Kindly I want to know if there any changes in some solvers like ODE113?
Recently I have updated matlab to 2023b version and tried to run a script that I have excuted it before with nothing changed on older version of matlab, the script contains solving DAE system Ax = B, with ill-conditioned A matrix, using ODE113 of an older version it was working with conditiong number was around e-21. my results using older version was compared to some other CAEs (figure below) and they were identical, so I do not know what is the issue in 2023b, any help please?Kindly I want to know if there any changes in some solvers like ODE113?

Hi,
I’m trying to modify the UAV Package Delivery project such as it allows multiple waypoints while avoiding obstacles, using QGroundConrol. Until now I have done these:
-modified replaced FollowWaypoints with the guidance from FullGuidanceLogic

However, MissionData input must be bus signal "uavPathManagerBus"

Currently, the MissionData comes from the function that contains the OA algorithm:

function [y, DTD, needHover] = computeLPWaypoints(mission, Steer,UAVState)
%#codegen

Wp1 = [mission(1).position’ mission(1).params(4)];
Wp2x = mission(2).position(1);
Wp2y = mission(2).position(2);
needHover = false;

% Follow obstacle avoidance steer direction when UAV is above 5 meters
% above ground
if (~any(isnan(Steer)) && (UAVState.z < -5))
if (Steer(5) == 0)
% Compute look ahead point 6 meters along the steering direction
LAP_local = 6*Steer(2:4)’;
% Follow yaw command from obstacle avoidance
yaw = Steer(1);
LAP = [LAP_local yaw] + [UAVState.x, UAVState.y, UAVState.z, 0];
if(isnan(LAP(4)))
LAP(4) = 0;
end

y = [ Wp1(1,:) ; LAP ; Wp2x , Wp2y , 0 , LAP(4) ];
DTD = norm([Wp2x Wp2y] – LAP(1:2));
else
% Rotate in place
y = [ Wp1(1,:) ; UAVState.x, UAVState.y, UAVState.z Steer(1); Wp2x , Wp2y , 0 , Steer(1) ];
DTD = norm([Wp2x Wp2y] – [UAVState.x, UAVState.y]);
needHover = true;
end

else
% If there is no good steer direction or UAV is too low, fly up
y = [ Wp1(1,:) ; UAVState.x , UAVState.y , UAVState.z-2 , 0 ; Wp2x , Wp2y , 0 , 0 ];
DTD = norm([Wp2x Wp2y] – [UAVState.x, UAVState.y]);
end

if(DTD<5)
% When close to target point, switch to landing
y = [ Wp1(1,:) ; Wp2x , Wp2y, -11 , 0 ; Wp2x , Wp2y , -1 , 0 ];
end

end
I get this obvious error when I try to run the simulation:

I have tried sending the sigal from the GCS dirrectly into the MissionData (as expected), but then the quadcopter just flies back and forth around the first waypoint of the mission:

I would very much appreciate any advice on how to move further with this.

Hello,
I am struggling with figuring out how to pass variables from a callback function (using ButtonDownFcn) to my main script.
Below is a simple example where I am trying to modify the example script from:
https://nl.mathworks.com/help/images/measure-distances-in-images.html

I simplified it below to just make the first function work and have two examples below:
– the original line (LINE A below), which doesn’t pass my variable back and doesn’t seem to allow me to define further output variables. Adding variables (double) to hIm also doesn’t work (I guess because it is an image object?)
– the simple line (LINE B below) works to pass the output variable, but is not an option because it doesn’t use the ButtonDownFcn anymore (which I need later).

clear all
close all
clc
im = imread(‘SENIAM_EMGEP1.jpeg’);
% Gather data about the image, such as its size, and store the data in a structure that you can pass to callback functions.
sz = size(im);
myData.Units = ‘pixels’;
myData.MaxValue = hypot(sz(1),sz(2));
myData.Colormap = hot;
myData.ScaleFactor = 1;
% Display the image in an axes.
hIm = imshow(im);
% Specify a callback function for the ButtonDownFcn callback on the image. Pass the myData structure to the callback function. This callback function creates the line objects and starts drawing the ROIs.
hIm.ButtonDownFcn = @(~,~) startDrawing(hIm.Parent,myData); %% LINE A
myData = startDrawing(hIm.Parent,myData); %% LINE B

function myData = startDrawing(hAx,myData)
myData.test = 2;
% Create a line ROI object. Specify the initial color of the line and
% store the |myData| structure in the |UserData| property of the ROI.
h = images.roi.Line(‘Color’,[0, 0, 0.5625],’UserData’,myData);
end

I have had a similar issue with callback functions and thought it was time to seek help.
The answer provided here (https://nl.mathworks.com/matlabcentral/answers/563102-passing-a-variable-from-a-call-back-function-matlab-2020a) doesn’t allow me to figure it out and I want to avoid using global variables.

I wrote an app in 2023b, but after installing 2024a the figure doesn’t appear the same, and some of my UI controls actually fall off the figure in 2024a. Below is a simplified example of the issue.
Here is the code I ran in both versions:
fig = uifigure(Name="This is in 2023b");
% fig = uifigure(Name="This is in 2024a");
lbl = uilabel(fig);
lbl.Text = "This is a label";
lbl.Position = [20 200 100 60];
Here is a screenshot of the outputs side-by-side:

As you can see the font and the spacing in 2024a is slightly larger, as if it is scaled differently. And it’s not just with UILables, the size and spacing is larger for all objects in 2024a compared to 2023b.
I reset all default groot settings with reset(groot, "default")
I recursivly cleared all personal settings with [setting].clearPersonalValue
But I still get this result.
It’s a fairly large and complex app with a lot of ui controls and I don’t want to rewrite it because if this.
Is there a setting somewhere I’m overlooking, or something else I’m missing?I wrote an app in 2023b, but after installing 2024a the figure doesn’t appear the same, and some of my UI controls actually fall off the figure in 2024a. Below is a simplified example of the issue.

Thank you in advanced!Dear All,
I am trying to solve a multivariate function by using the Newthon’s Method. However, I get an error message in the lwhen I run my code (exactly in newtons_method file), and I could not figure out what is going on. Here is the files that I am using:

if (nargin < 4) || isempty(opts) || ~isfield(opts,’return_all’)
