How do I solve “pyrunfile is not suppoted” error in MATLAB Function ?
I got these errors in MATLAB Function. I tried everything but I couldn’t figure out how to solve. I’m not sure.
Could you give me any advice? I’d be happy if you could tell me why this happens and where I’m missing.
Also, I’m now executing this model on MATLAB Online.

Is it possible to make Machine Learning model to predict multiple outputs with Statistics and Machine Learning Toolbox?
I’d like to create a model to predict two output signals based on the following seven input signals, by using Statistics and Machine Learning Toolbox.
This csv is a the data (about 4,200 rows) used as training data.
This data is a time series every 0.025 seconds.
I think the model type is Regressin model if you create a model from this data.
(Data type of each Signal is double type.)
Input Signals：
V_TGT_Vehicle
P_DCDC_PNT_W
P_HVAC_PNT_W
SOC_BT_Hi_PNT_per
open_accel_Driver_per
open_break_Driver_per
w_MG_PNT_radps
Output Signals：
trq_MG2_tgtCalc1
trq_MG2_tgtCalc2
I’ve been going through Statistics and Machine Learning Toolbox documentation, I’m not sure if it’s possible to create a machine learning model like above.
I’d like to export the model as Simulink block.

Colormap generated using the information of different arrays
Hello everyone
I am trying to plot the data in five different matrices in the same graphic. Interestingly, the elements of these matrices are not equal to NaN just in the spatial domain where, each of them, should exists. In principle, if the matrix element (i,j) of one of these matrices is different from NaN, it would not be again non-NaN in the other data arrays at (i,j). The five different matrices can be found here.
I would like to make the NaN elements to be completely transparent. As you can see, I am attaching a colormap, "Colors.txt", which is not white at the middle. I do not know if that makes any difference.
I am plotting the system as follows:
p1=uimagesc(Space_a,Space_b,mz_Tetra_1_Data);
set(p1,’alphadata’,~isnan(mz_Tetra_1_Data));
hold on
p2=uimagesc(Space_a,Space_b,mz_Tetra_2_Data);
set(p2,’alphadata’,~isnan(mz_Tetra_2_Data));
p3=uimagesc(Space_a,Space_b,mz_Penta_1_Data);

print() and saveas() produce svg files where text is stored as paths and not text – how to overcome?
I am trying to export an .svg image of a matlab figure (see attachement) to convert it afterwards in Inkscape to a .pdf_tex file to include it in a nice way into my latex document. However when trying to export it with eiter print() or saveas() it always saves the labels as vector graphics paths and not as text. This makes it afterwards unfeasible to save the text of the image (labels, etc) as propper text for the latex file.
I have so far tried multiple things:
% Open the figure
openfig("25m_baseline_smoothing.fig");
h = gcf();
h.Renderer = "painters"; % To make sure I have a vector image
% Trial 1
print("25m_baseline_smoothing","-dsvg"); % Produces paths
% Trial 2
saveas(h, "25m_baseline_smoothing","svg"); % Produces paths, not text
Futher I also tried to save the figure with the menu in the figure dropdown menu (File > Save as…). I also tried to directly export the figure with matlab2tikz. This is not a solution either as matlab2tikz can’t handle a tiled layout yet.
Is there a way to overcome this problem and export the labes directly as text to the .svg image?

How to optimize IF statement with Multiple Conditions.
Hello,
I have five Tables (T1 to T5) and Conditons CR ranging from ( 0-4) . When I process a files each file may have one condition in it or multiple conditons. For example ( it could have Condition 3 or in the next file it could be 0,2 & 4). Which ever condtiion is satisfied that particular table (if one condition) and (Multiple table Verticat into one final table).
I tried using multiple methods like
1) If any or all statments didn’t work.
2) if I have to use ismember then I could have make multiple array of condition hard coded into the script. Example: Condition:if ismember([1 2], CR]’
Final_Table = verticat(T2;T3).
Could someone suggest a robust and quicker way.
If possible provide with a Script sketon or example so It could be understood better and also your time and effort is well respected.

Smooth noisy data whilst keep absolute minimum and maximum values
I have a reasonably noisy signal (almost sinusoidal) that I am smoothing using sgolayfilt.
I am using a polynomial of 2 with a frame length of 901.
I am happy with the smoothing using this frame length.
However, there are several parts of the signal that need to have (correctly) a minimum value of zero.
When I smooth the signal the value of the minima are no longer zero. The lowest value of the smoothed curve at the minima takes a non-zero value, that might be positive or negative.
If I "shift" the curve then only one of the minima is zero.
Is there a method to smooth curves whilst keeping absolute minimum (and maximum if required) values? Or is it always a trade-off (I could trace the signal by eye very well, using a drawing package, keeping the minima, but I want to automate the process with matlab)

Want to remove white patches of a image

What i am planning to do is find out the region of high white intensity that is with RGB values over 220 and then replace them by the average shade of the pixels around them, thus removing those white patches. Is this possible?

model reduction from a database created with xfoil
Hello community,
i have created a database with xfoil (2d airfoil panel code with an boundary solver).
The database is saved in this format:
% L lift
% D drag
% al angle of attack
% thick thickness of the airfoil
% camber camber of the airfoil
% Ma Mach number
% Re Reynolds number
L = db_L(al, thick, camber, Ma, Re);
D = db_D(al, thick, camber, Ma, Re);
The easiest way is a lookup-table, but i am looking for a more sophisticated approach like a POD (proper orthogonal decompositon) to identify e.g. how sensitive the thickness affect the lift.
if every input variable consist of 16 values, the database has 16^5 entries, and i could create Matrix of 1024 x1024 for the POD analysis.
but how could i compare the results of the modes with the data base? e.g. the deviation of the lift for a specific case.
PS: is there an application or something in Matlab which could help me?
best regards

I have to use curve fitter for z = f (x, y), but I don’t have values for z(2, 4), z(3,3) and z(3,4) (red one).
In the workspase variable (matrix Z) these blank places automatically take values, which is zeros. Is there any instrument to ignore these zeros and the regression analyses to be made only with the available z values. In other words to ignore the three zero values in the down right corner? May be something with the weights instrument? If I simply use the matrix with zero values, without any additional actions, of course the regression method uses these z(2, 4) = 0, z(3,3) = 0 and z(3,4) = 0 and the results are unacceptable.Dear Community Members,

I want model a datacenter load from time series power consumption and then connecting it to AC distribution three phase system
Problem I am facing is when I use importedin MATlab and model it as a load using controlled current source and then adding an inverter , my swing bus (From IEEE 13 bus test system) is having Dc bias/ offset instead of balance volatges. I am trying to analyze transient behaviour dueto sudden high current requirement. Please guide why I am getting this problem.Problem I am facing is when I use importedin MATlab and model it as a load using controlled current source and then adding an inverter , my swing bus (From IEEE 13 bus test system) is having Dc bias/ offset instead of balance volatges.

What is the setting in Production Server for auto deployment and how do I set this up?
I could not find a place in Settings section in the Production Sever Dashboard to enable or disable auto deployment, and if I need to add the options through advanced section, what I should put there? Do I need to restart the server/instance after I add the auto deployment configuration?I could not find a place in Settings section in the Production Sever Dashboard to enable or disable auto deployment, and if I need to add the options through advanced section, what I should put there?

Examples missing from requirements toolbox installation
I am trying to open the "Link test case reqs Example" with the command openExample(‘slrequirements/LinkTestCaseReqsExample’), but the only examples I have installed are "ImportAndEditRequiermentsWordExample" & "VerifyAShortestPathAlgorithmExample". There should be way more than 2 according to the doccumentation.I am trying to open the "Link test case reqs Example" with the command openExample(‘slrequirements/LinkTestCaseReqsExample’), but the only examples I have installed are "ImportAndEditRequiermentsWordExample" & "VerifyAShortestPathAlgorithmExample".

Accessing Pixhawk 6x parameters when building firmware for SRXL2 connection
I am attempting to get the Pixhawk 6x to receive data from a new spektrum receiver that utilizes SRXL2, the process required for getting the SRXL2 protocol to work involves setting certain parameters to different values, namely:
Set SERIAL4_PROTOCOL = 23
Set SERIAL4_OPTIONS = 4
Set RSSI_TYPE = 3
However, when looking at the parameters avaialble in Qground control or mission planner, these parameters are not present. Additionally, there seems to be some kind of text file called uart.txt that the serial parameters are attempting to read from but it detects nothing when loading. Is there any way of adding these parameters to the pixhawk during the firmware build process? Or is there a specific means of configuring the TELEM2 port for a true UART connection. As this is the only way I can get the SRXL2 to connect to the pixhawk when it is running a simulink model (fmu_v6x_fixedwing).I am attempting to get the Pixhawk 6x to receive data from a new spektrum receiver that utilizes SRXL2, the process required for getting the SRXL2 protocol to work involves setting certain parameters to different values, namely:
