Default data division in trainAutoencoder
Hello,
Can anyone explain why the default data division for the trainAutoencoder function (example usage here Train Stacked Autoencoders for Image Classification) uses the default data division method "dividetrain", i.e., data division is training only, rather than a training/validation/testing one (e.g., dividerand, divideint, etc.)?
Thanks.Hello,

I want to perform this time derivative?

Using a newer version of plot (ezplot to fimplicit or fplot)
See https://uk.mathworks.com/matlabcentral/answers/327895-how-do-i-plot-a-circular-arc-with-given-two-endpoints-and-radius#answer_272169 for context
Using the answers from this question I was able to edit the code from the link above to get the general arc shape that I wanted.
However, I have a few issues, mainly down to my lack of experience:
1) ezplot isn’t recommended for the type of shape, so fplot and fimplicit are suggested as alternatives, and I’m not sure how to change ezplot over and maintain the same arc image
2) I need a functionality to change the thickness of the line which it doesn’t currently have
3) With this code it isn’t necessary but being able to plot multiple similar arcs on the same graph is also important
I’ve looked through the help centre for ezplot, fplot and fimplicit and I’m really not sure where I’m going wrong.

How to keep the original layout in the full screen or when maximizing the GUI of a MATLAB App ?
Hello everyone,
I am desinging an App in the MATLAB App Designer, I am using MATLAB R2023a, and I am working on a Windows operating system.
After finishing the design of my App, I have noticed that when running the App, the layout of the designed GUI is lost when the GUI is on full screen or when it is maximized. Please see the attached Capture1 and Capture2 for the layouts of the GUI (Capture1 shows the layout when the GUI is minimised, this is the original layout that I have designed, and Capture2 shows how the layout is changed when the GUI is on full screen or when it is maximized).
I want that the GUI keeps the original layout that I have set when I was designing the App in the App designer, when the GUI is on full screen or when it is maximized.
I have found on some answers of MATLAB Central that I Should select for WindowState "fullscreen" or "maximized" and that I should also select "Resize" and "AutoResizeChildren" in the Settings of POSITION. I have done all that, please see the attached Capture3, but I still have the same problem.
Does anyone have any solution for this problem ?
Many thanks to everyone in advance.Hello everyone,

how to prepare the data set for boxLabelDatastore function using image labler APP
I have a data set prepared by image labler APP. The format of the bounding box is different to the example showing on the matlab page.

I wrote some codes to convert them, but not very successful. There are either single or double quotation marks in my table and

The size of bounding box data must be M-by-4, M-by-5, or M-by-9, where M is the number of boxes in each table element. The column in the training data table that contains the bounding boxes must be a cell array.
My questions are:
1) How could I convert them into a cell array without ‘ or ”
2) Is there a easy way to label image and produce the dataset that mataches the example data set?

DC CURRENT LIMITATION IN FOC OF PMSM
I am trying to simulate vector control of pmsm .The id iq PI takes care of the phase currents.I need to limit power also without using a PI because I already have speed PI and another PI used for FLUX weakeaning (voltage regulation based).So if have to implement it in hardware there would be 5 PI if i use a PI for DC current which is undesirable as my MCU is not that powerful.Is there any other logic to implement DC current limiting without using a PI in FOC of PMSMI am trying to simulate vector control of pmsm .The id iq PI takes care of the phase currents.I need to limit power also without using a PI because I already have speed PI and another PI used for FLUX weakeaning (voltage regulation based).So if have to implement it in hardware there would be 5 PI if i use a PI for DC current which is undesirable as my MCU is not that powerful.Is there any other logic to implement DC current limiting without using a PI in FOC of PMSM I am trying to simulate vector control of pmsm .The id iq PI takes care of the phase currents.I need to limit power also without using a PI because I already have speed PI and another PI used for FLUX weakeaning (voltage regulation based).So if have to implement it in hardware there would be 5 PI if i use a PI for DC current which is undesirable as my MCU is not that powerful.Is there any other logic to implement DC current limiting without using a PI in FOC of PMSM dc current, foc, pmsm, powerlimit MATLAB Answers — New Questions

Is the “kinematicTrajectory” function correct for calculating angular velocity?
Hello there,
I noticed that the “kinematicTrajectory” function calculates angular velocity from the body frame to the earth frame using the “rotatepoint” function. The “rotatepoint” function can be formulated with the Rzyx rotation matrix.
where is roll, is pitch, is yaw.
However, some papers [1] and references [2] use the transfer matrix T.
Does anyone know which is correct?

How to add math symbols to Live Script text?
Some five years ago, I used Matlab as a handy "math typewriter": it was easy to insert symbols to text without remembering their LaTeX keywords. I just opened a dropdown list and picked what I needed.
Now, I have installed Matlab R2023b to my new laptop, and I can not find that functionality any more.
Is it still there, and I’m just not able to find it?
Or, has it been removed, and I’b better just learn my LaTeX?
Or, should I install some extra library to get is working again?
Or, could I return to the old Matlab version (maybe Matlab 2018 or something like this)?Some five years ago, I used Matlab as a handy "math typewriter": it was easy to insert symbols to text without remembering their LaTeX keywords. I just opened a dropdown list and picked what I needed.

How do I programmatically set the parameters of a Get Transform block?
I want to programmatically set the rigid body tree parameter of a get transform block and I tried doing that using the set_param function. If i write the value of the parameter as a string:
set_param(strcat(modelName, ‘/Get Transform’), ‘RigidBodyTree’, ‘DOF3_Arm’) %DOF3_Arm = importrobot(‘RobotStructure’);
the associated field in the Block’s Parameter will just have a string but no rigid body tree, and if I use a variable instead of the string i get the following error:
Error using Script_function_back2WF
Invalid setting in Get Transform block (mask) ‘Get Transform’ for parameter
‘RigidBodyTree’
What is the correct way of setting this parameter? Thank you in advance!I want to programmatically set the rigid body tree parameter of a get transform block and I tried doing that using the set_param function. If i write the value of the parameter as a string:

Multiple PID tuning in order to control all four states in the inverted pendulum model
Hi!
I have to control the four states of the classical nonlinear inverted pendulum on a cart model (position and velocity of the cart, angle and angular velocity of the pendulum) in Simulink through PID control. Being on a cart it doesn’t have to go through the swing up, the initial condition for the angle is -0.5 (desired angle with a small perturbation), so it’s just the balancing problem.
This is my Simulink control scheme:
My implementation works as it should, but I had to manually tune the four PIDs because I wasn’t able to obtain the same system with just one controller (if I give a vector of the four errors as input to a single PID block designed with a vector of four gains it messes up and creates a 4-dimensional output instead of executing the row-column product) and I tried everything but couldn’t tune the multiple PIDs at the same time. Of course, the tuner app embedded in every PID block is useless in my case since the output of the system isn’t just depending on a single PID’s control input. I wonder if I can automatically find the optimal choices for the PID controllers, can someone help me?Hi!

Fusing layers of a color image
