Findings experimental values closest to the setpoint value
Hi there,
I will try to explain the issue I am having to the best of my ability (I have also attached an example excel for clarity). Essentially, in my experiment, I am trying to analyze the loads achieved at specific angles based on setpoint angles I am feeding the actuator (each case has different setpoints but in the case I am introducing here, the setpoints go from -50 to 10). There are two actuators in this example that I am testing (Compu1 and Compu2) (there are actually about 50 overall I’m testing but in this example, there are 2), each with a different achieved angle value and its equavlient load measurement. What I am trying to have Matlab do is export the load value of that actuator that best represents the neareast achieved angle based on the set point fed into it.
Reason for that, is that when I plot the loads achieved of the two actuators, my X axis (set point angle) will have ranging values for each individual actuator so I’m trying to essentially "normalize" the data based on my set "angles to plot" column in excel (increment of 0.1 degrees) and I would want matlab to just export the nearest value to that column so that each actuator can be properly plotted together against the same X range for direct comparsion.
I hope that made sense. Again, this example only includes 2 actutors but I would appreciate it if the solution can be tailored towards an X number of actuators.
Thanks so much in advance!Hi there,

Plotting a Simulink reinforcement learning environment
Hello there,
I have declared an environment starting from a simulink model:
env = rlSimulinkEnv("main","main/RL Agent",obsInfo,actInfo);
Then i have properly defined the training options and i have executed the training.
Now, I would like to plot the environment during the training process. In the help center i have found the possibility to use create a plot function exploiting a callback on environment update.
Are there any ways to do something similar also for the rlSimulinkEnv command without defining a custom environment with all the dynamic equations?
Thank you in advance.Hello there,

Issue on running PV array/VSC concurrently with Synchronous Machine
Hello,
I am having some trouble in simulating on Simulink this two blocks together:
PV array / Universal Bridge (VSC average model) – I don’t know which is responsible for the errors….
Synchronous Machine
I am able to run these blocks separately (by commenting one, then running the simulation and later commenting the other and running again) so I know it isn’t a problem with parameters and neither a singularity in the synchronous machine, which is one of the errors message that I receive when I try to simulate them together.
Also I know that, probably, it isn’t caused by the dynamics of the system because, as you can see in my model, I put a breaker on the PV array, and tried to run with it open, so that it doesn’t affect the dynamics of the system/synchronous machine, and even so the simulation goes wrong.
Does anybody knows what may be happening? Did this occur with you too? How can I solve it?
Please, try to run the cases I just said and see for yourself.*
The error happens at t = 0.0566 when both PV and SM are connected and non-commented.
*First, run "init_var.m" for setting the system parameters and variables.Hello,

How to order a Shapes object with actxserver for Excel?
I am trying to send an image I input into an Excel file to the back of the Shapes object. I have tried two different methods.
Method 1: Selection and Send to Back

objExcel.Workbooks.Open(excelFileName);
myshapes = objExcel.ActiveSheet.Shapes;
N = myshapes.Count;
ShapeToBack = myshapes.Item(N);
ShapeToBack.SendToBack();
The problem is that the .SendToBack function is not recognized. I did test out the Send To Back option in Excel and this did reorder the image in the myshapes. I was hoping to do that programatically, but I can’t find a way to do it in MATLAB.
Method 2: Copy Delete and Paste
objExcel = actxserver(‘Excel.Application’);
objExcel.Workbooks.Open(excelFileName);
myshapes = objExcel.ActiveSheet.Shapes;
N = myshapes.Count;
for j = 1:N-1
ShapeToCopy = myshapes.Item(j);
ShapeToCopy.Copy();
myshapes.Item(j).Delete

B = [0 0 0 …]
Sample time = Ts = 1e-6
B = Ramp A
Maybe I need a toolkit that has a premade ramp block that takes an input and sets upper and lower limits.
Thanks,
DavidI have a simulink variable that has 63 elements. I would like to ramp each element in the variable proportionally from 0 to the value of the variable.
For example
A = [22 17 39 …]
B = [0 0 0 …]
Sample time = Ts = 1e-6
B = Ramp A

Issue with Exporting High-Resolution Mineral Images from CorelDRAW for MATLAB Processing
Image Preparation: I have outlined the minerals in CorelDRAW, and the quality looks excellent within the software.
Exporting Issue: When I export the image to PNG format, the resolution becomes pixelated, making it unsuitable for further processing in my MATLAB code.
Code Requirements: My MATLAB code accepts PNG, TIFF, JPEG, and BMP formats.
PNG Issue: The resolution is poor and pixelated.
Other Formats (TIFF, JPEG, BMP): The background of the image is selected, which is not desired.
Question:
What settings should I use in CorelDRAW to export a high-resolution image in PNG format without losing quality?
How can I ensure that the background is not selected when exporting to TIFF, JPEG, or BMP formats?
Any advice or tips would be greatly appreciated!

Network doesn’t work on test image
Hi all.
I’m trying to use and train a pretrained network (YOLO v2) on my own dataset (80 images).
I divided my set in training, validation and test, but network works correctly only on these images and not on other images that aren’t in these set.
What can I do? I have to test my network only on the images that I have labeled?

Live script fprintf temporarily not printing whole line
While doing a bunch of file IO in a Live Script, and printing with fprintf, sometimes the line does not complete printing. Temporarily, it looks like the image below until the next iteration begins.
I was able to sort of recreate the effect with the code below, but what can be only a flicker in the execution of this snippet is much more noticable on my other project.
for i= 1:10
fprintf("Hello %dn",i)
B= inv(rand(3000)+ 2*eye(3000));
end
