Matlab code does not run past a certain point: i.e. buffers at a certain line of code
So I’m trying to solve a problem (attached below) and I’ve written the code (below) to solve it. When I go to run the code it gets stuck at the following line:
% Solve the ODEs numerically
%[t, y] = ode45(odeFunc, [t0, 1.66*3600], [r0; v0], options);
It fully ran once, but continues to not run.
This is the problem:

Prediction based on ClassificationPartitionedModel
Hi all,
I have a predictor matrix X and binary response y (1000 observations) and want to use support vector machine (or other machine learning techniques built in Matlab, i.e., fitctree, fitcdiscr, fitcknn, fitcnet) to train the classifier based on 10-fold cross-validation.
My idea is to use 1-999 observations for cross-validation training and testing, and use the best classifier to predict a single out-of-sample y based on 1000th X. How can I do that?
Without cross-validation, I can simply use predict(.) function in Matlab to predict a single y based on 1000th X. However, this is not allowed when cross-validation is used. For a ClassificationPartitionedModel, the function kfoldPredict(.) should be used. The problem is, I am not allowed to specify the X when using kfoldPredict.
Is there anyone know the answer?
Many thanks.Hi all,

Why do I get an unhelpful error message when assigning a “struct” only to the end of the last structure array entry initialized by empty brackets?
I am initializing an empty structure array using empty brackets:
>> myStruct(3).myField = [];
Then, all the initialized structure arrays are of type "double":
>> {class(myStruct(1).myField), class(myStruct(2).myField), class(myStruct(3).myField)}
ans =
1×3 cell array
{‘double’} {‘double’} {‘double’}
Why do I get an unhelpful error of "Conversion to double from struct is not possible" only when appending a "struct" to the end of the last array entry?
For example, the following code snippet executes without an error, which changes the class of the first and second entries of "myStruct" to "struct":
>> myStruct(1).myField(2) = struct(‘myVar’, 3);
>> myStruct(2).myField(2) = struct(‘myVar’, 3);
>> {class(myStruct(1).myField), class(myStruct(2).myField), class(myStruct(3).myField)}
ans =
1×3 cell array

However, executing a similar line of code for the last entry of "myStruct" does throw an error:

How to replace values in a table with the outputs of another code?

I got and error originally saying that the right hand side needed to be a table or an array (Originally i just had the "minPModel" and such but since replaced them with the new table "MinMaxTab" and it still won’t accept it).

Two Arduinos with Two Simulink Model
Hi,
Please let me know if I am doing something wrong or it is just the limit of Matlab.
I have 2 Arduinos, Uno and Due.
I created two different Simulink model that 1, Uno, is going to be the output as sending digital signal. The second model is going to be the Due as an input to read what is on the pin.
When I open them both, set the Hardware, set the comport, and ran. Only one of them runs not the other.
Once one of them runs then the another Simulink model thinks that it needs to be connected to the currently connected device.
For example, if I run the Uno model, then the Simulink model (A) connects to Uno successfully. However, while the Due is connected, run the Due Simulink model (B) then it shows me an error saying that sorry I can’t connect to Uno. I told the Simulink to connect to Due at a specific port but it is keep doing this.
Has anyone have experience in setting two arduinos and two simulink model separatly?

How to resize axes programmatically within a GUI built with uifigure and uigridlayout?
Hi everyone,
I’ve been building a GUI based on a uifigure and the matlab.apps.AppBase tools. It’s not built in App Designer, I do it programmatically. I use a uigridlayout to position my various items; it works quite well for most things, but I’m having trouble with uiaxes.
These uiaxes are located within the uigridlayout, but I need to make a slight size adjustment after they’ve been created. I just need to adjust the width, I know by how many pixels to adjust it. If I run my app by typing "app = appName();" in the command window, the app shows up, the uiaxes are not adjusted. I then issue the command in the command window: "app.myAxes.Position(3) = app.myAxes.Position(3) – boxWidth;", which does exactly what I need it to do.
However, adding that line of code in the code that builds the actual GUI does not work, no matter where I try to put it. I’ve set AutoResizeChildren of the uifigure to off, no luck. I’ve searched here, but nothing I found seems to work.
So how do I get my app to execute that particular line of code?

I would like to change this graph by keeping 4 boxplots for 4 and 6 classes, and then having only blue and red boxplots for 8 classes.I would like to change this graph by keeping 4 boxplots for 4 and 6 classes, and then having only blue and red boxplots for 8 classes.

Matlab function only giving me 1 output
I have a function but its only giving me 1 output as an answer.
>> theta = 0:0.01:90;
>> Vmax = sqrt((0.25.*cos(theta).*9.8.*(sin(theta)+0.2.*cos(theta)))/(cos(theta)-0.2.*sin(theta)))
Vmax =
0.1514
I want to plot this on a graph but it only interprets the function as having 1 value. I’ve done functions this way before like if i just say
>> x = 0:0.01:pi;
>> y = sin(x);
it works fine so why is my Vmax just giving me 1 value.I have a function but its only giving me 1 output as an answer.
>> theta = 0:0.01:90;

Error when buliding PX4 firmware with some deactivated modules
Dear all,
I am currently using simulink to impememt my filght controller into Pixhawk 6x. At the step of building PX4 firmware I followed this tutorial https://ch.mathworks.com/help/uav/px4/ug/disable-control-modules.html. to avoid flash memory overflow issues, since building a default PX4 firmware itself takes already 99% of the total flash usage.
I change the code
CONFIG_MODULES_MC_ATT_CONTROL=y
to
CONFIG_MODULES_MC_ATT_CONTROL=n
in the file default.px4board.original and resave it as a new file hil.px4board. in the same folder.
In the Hardware Setup screen I tried to build ths new firmware but there is then an Error in cmd window,saying:

Have you met this issue before and how did you solve it?
any suggestions or advices are welcome.

Y.Z. Dear all,
I am currently using simulink to impememt my filght controller into Pixhawk 6x. At the step of building PX4 firmware I followed this tutorial https://ch.mathworks.com/help/uav/px4/ug/disable-control-modules.html. to avoid flash memory overflow issues, since building a default PX4 firmware itself takes already 99% of the total flash usage.
I change the code
CONFIG_MODULES_MC_ATT_CONTROL=y
to
CONFIG_MODULES_MC_ATT_CONTROL=n
in the file default.px4board.original and resave it as a new file hil.px4board. in the same folder.
In the Hardware Setup screen I tried to build ths new firmware but there is then an Error in cmd window,saying:

Looking for help with labelling groups
Hey everyone,
so far I’ve read all Matlab entrys on adding/creating categories and/or labels but I haven’t found something fitting that works for me. I have a set of data in 178×13 double format, the variable names in a 1×13 cell format and the group classification in a 178×1 double, which ist just 1 2 and 3. In different projects I had a 178×1 cell instead containing the names of the groups and I would use that to generate a double using findgroups. However, now I would like to do the reverse action and generate a 178×1 cell value with the names instead of numbers. Num2Cell does not work here of course because I would like to tell Matlab to put "GroupA" for every 1 in the group classification 178×1 double and "GroupB" for every 2 and GroupC for every 3. I have information that the first 59 belog to GroupA etc, but I don’t know how to implement that either. Maybe it’s the language barrier but I really don’t even know what to search for anymore. Any help is much appreciated!Hey everyone,

Control quiver arrow head width vs height.
Hi, I have a quiver plot where the arrow heads are incredibly wide by default, so I used "MaxHeadSize" to shrink them to a reasonable size. Also, the scaling behavior is set to 0 because I want them to connect the way they do currently. The downside is that now, instead of looking like arrowheads, they almost look like horizontal bars. I’m wondering if there is a way to control the head length independently of the head width.Hi, I have a quiver plot where the arrow heads are incredibly wide by default, so I used "MaxHeadSize" to shrink them to a reasonable size.

How to search array in array same values?
Hello,
I create an array below;
bigArray = rand(1,150);
bigArray(1,15:19) = [1 1 1 1 1]’;
bigArray(1,25:29) = [1 1 1 1 1]’;
bigArray(1,75:79) = [1 1 1 1 1]’;
bigArray(1,105:109) = [1 1 1 1 1]’;
bigArray(1,65) = 1;
bigArray(1,5:6) = [1 1]’;
I want to find [1 1 1 1 1]’ array indexes. But I run the code;
idx = find(ismember(bigArray,[1 1 1 1 1]’))
I want to see as an output; [15 16 17 18 19 25 26 27 28 29 75 76 77 78 79 105 106 107 108 109]Hello,
