Match row and column in a number of excel file and return the value in the cell
Hi!
I am trying to process some data located in separate excel files (a few hundred). The files consist raw data directly downloaded from a data base in the form of books/files with export and import data during a period of time.
The actual location in the sheet varies between the documents, meaning it needs to be a solution that searches and find the value in the sheet. Ideally I would like to construct a number of loops that:
Finds the correcponding value that matches a row and a column. F.e the match between the row with name "China" and the column "Exported value in Q4 2015" and return the value (or the cell index).
Locate the value or cell index in question and return the value of it, and the correcponding 3 values on the row in question. If the value is located in C4, I would like to find the total value for C4+ D4+E4+ F4.
The end goal is a loop that search through all files and repeats the procedure above.Hi!

Simulink RT Instrument – How to set maximum amount of data received with getBufferedData() and how to stream each signal?
I use Instrument with buffer mode and simulating random model with Simulink RT.
Here is the code for initializing instrument:
tg = slrealtime(‘TargetPC1’);
removeAllInstruments(tg);
hInst = slrealtime.Instrument(‘test.mldatx’);
hInst.addSignal({‘test/constant_block’}, 1);
hInst.addSignal({‘test/demux_block’}, 1);
hInst.addSignal({‘test/gain_block’}, 1);
hInst.addSignal({‘test/from_block’}, 1);
hInst.BufferData = true;
addInstrument(tg, hInst)
and getting datas while RT simulation is running with:
buffer_map = getBufferedData(hInst);
buffer_values = buffer_map.values
1 – Since the buffer only clears when I use getBufferedData(), If I don’t use this function for a while, it tooks many seconds to get all the data from buffer, but I only need latest data. Therefore, can I only get latest data and shorten the time or can I decrease the buffer size to shorten the time?
2 – I am adding 4 signals above code, outputs of constant, demux, gain and from blocks, but I can only get gain block’s output signal data and I can validate these 3 signals are not added to target instrument by using validate(hInst, ‘test’) and I can see warnings when I try to add them. I think they are optimized because these blocks is just for a connection, not for a mathematical operation. Is there a way to stream all the signals I have added?
I use Python-MATLAB bridge, so I can’t use callback method too.

cosine of a matrix returns weird values.
I’m trying to plot a few forces that chance because of an angle. I’ve defined the changing angle as beta which is a matrix. Than i’m calcultating two different angles which matter for the calculation of the forces. And for these forces i need, for example, the cosine of angle alpha. The angle of alpha changes between 90 and 0 degrees. But if i take the cosine of this matrix it returns weird numbers. Negative numbers, like -0.4481. It should start at 90 and cosine 90 equals 0 but it doesn’t. Does anyone know what is going on?
Fad = 240
beta = 0:1:180; % Angles
gamma = 180 – beta;
alpha = 0.5.*gamma;
w = cos(alpha); % Cosine and tanges of said angles
x = cos(gamma);
y = tan(alpha);

Switching elements in 3D image(xy) dataset to export yz and xz images
I am working on (x*y)*z (eg. 300x300x300 pixel) binary image data set that gets imported as a multidimentional array.
For directional open porosity calculation I need to export YZ and XZ images for further calculation
A rough example on the layout(the numbers here would be 0 or 1 in actual data):
M(:,:,1) = [1 2 3; 4 5 6; 7 8 9];
M(:,:,2) = [10 11 12; 13 14 15; 16 17 18];
M(:,:,3) = [19 20 21; 22 23 24; 25 26 27];
for t1=1:size(M,3)
for i1=1:size(M,3)
YZ(i1,:,:)=M(:,:,i1);
end
end
for t2=1:size(M,3)
for i2=1:size(M,3)
XZ(:,t2,:)=M(i2,t2,:);
end
end
This produces the images in the YZ.
YZ(:,:,1) = [1 4 7; 10 13 16; 19 22 25];
YZ(:,:,2) = [2 5 8; 11 14 17; 20 23 26];
YZ(:,:,3) = [3 6 9; 12 15 18; 21 24 27];
I am facing the problem in the XZ planes, the last section produces only the required first page of the multidimentional array
the current output is
7 8 9
16 17 18
25 26 27
The required outout would be something like
XZ(:,:,1) = [7 8 9; 16 17 18; 25 26 27];
XZ(:,:,2) = [4 5 6; 13 14 15; 22 23 24];
XZ(:,:,3) = [1 2 3; 10 11 12; 19 20 21];
or the reverse
XZ(:,:,1) = [1 2 3; 10 11 12; 19 20 21];
XZ(:,:,2) = [4 5 6; 13 14 15; 22 23 24];
XZ(:,:,3) = [7 8 9; 16 17 18; 25 26 27];
I saw this question https://nl.mathworks.com/matlabcentral/answers/302683-switch-elements-of-the-2nd-and-3d-dimension-in-3d-matrix
But in my case permute() is not generating the required layout.

How to find lines that intersect at least 3 different points on Y axes with 2 % error range?
I have time series data which consists of the time and closing prices of a stock. To automatically find trend (or trend like) lines I tried best fit – poly fit (polyfit(x,y,1)). As it is known, lines passing through 3 or more points are considered as trend lines financially and these points must be the lows or highs in the data set. So to be able to find local lows/highs IsChange() function which finds abrupt changes in data seems to be useful.

Simscape AC Current Source issue
Hello Community,
I would like to simulate a street with Simscape, and i wanted to use a AC current source to supply from residents. As i learned it is the same issue with the simple AC Voltage Source, that even i use 3 phase breaker at both side, and wswitehced off, during the simulatin the status of the breaker is not relevant.
This is the subsystem is use:
There is the two 3 phase breaker (I iknow it is not necessary, but i dont have other idea), what is by default closed.
When i make a simulation with both breaker open status:
The value of the current is added even it is switched off. This should be the values, when the breakers are open ( i delete the 3 AC cource):
Every section i made an option to break the line, so i did it to see, and the result is, that even the breakers are in open position, it is still count:
Other, that i tried with closed breakers, and nothing change, therefore i think is is an issue with the calculation.
Do anybody have any idea what is goint on?
Thanks.
PS: The model works more less with the controlled AC source, but it is changing even i set the designated AC Current, SO therefore i would like to try another source.Hello Community,

Transpose SQL code into MATLAB
Hi,
I have an SQL query that is ok in Workbench, the results are I expected:
SELECT * FROM prices.prices WHERE (Var5 <= 125 and Var5 >= 124 OR Var6 <= 125 and Var6 >= 124 OR Var7 <= 125 and Var7 >= 124) AND (Var8 <= 6 and Var8 >= 5 OR Product <= 6 and Product >= 5 OR Var10 <= 6 and Var10 >= 5);
In Matlab I want to do a query in data base, based on 4 variables 2 min and 2 max values that search in 6 different columns . For only 2 variables min and max value work perfectly but if I add the other two variables to extend the selection in other three columns it failed to show wanted results.
This is the half working:
sqlquery = [‘SELECT * FROM prices.prices WHERE Var5 <= ‘,caseta2 ‘ and Var5 >= ‘,caseta1 ‘ OR Var6 <= ‘,caseta2 ‘ and Var6 >= ‘,caseta1 ‘ OR Var7 <= ‘,caseta2 ‘ and Var7 >= ‘,caseta1];

How do I solve this IndexError in ONNX Model Predict block?
I created this kind of a sample Simulink model with ONNX Model Predict.
I want to run the simulation with my simple ONNX model that I created with Pytorch.
Also I set Input and output tab of the block parameter like the below images.
Input tab
Output tab
then I run the simulation however I got this error.
Despite the same count of Input to ONNX model, this happens…
Does this ring a bell? I could figure out where I am missing…
I’d appreciate it if you could give me your advice. How do I solve?

regionZoomInteraction only works the first time, bug?
So I noticed this very weird thing which I think is a bug…
When the switch is on by default, the regionZoom works as intended. Then I turn it off, and rotate and zoom starts to work. And turn it on again, now the regionZoom cursor shows, you can select the area, but it doesn’t actually zoom.
It looks like regionZoom only works in the first instance. Second time onwards it doesn’t work. ZoomInteraction still works and this issue only applies to regionZoom.
Any thoughts? Can I add regionZoom as a standard option in the axes toolbar? That would do the job too.
function ButtonPushed(app, event)
ax=app.UIAxes;
if app.Switch.Value == "Off"
ax.Interactions = [rotateInteraction zoomInteraction];
else
ax.Interactions = [regionZoomInteraction zoomInteraction] ;

Replace FMU and reload it in the FMU block in Simulink
Hello everyone,
I have the following problem: I have added an FMU import block to my Simulink model and imported my FMU by specifying the path of the FMU. The simulation in Simulink with the FMU works so far. However, if I make changes in the external simulation software (I am not talking about parameters that I could change directly in Simulink) and replace the existing FMU in the Matlab path with a new one (with the same name), the FMU block in Simulink do not see the changes, even though they appear in the corresponding xml file. I can still simulate with the FMU, but changes in parameter values between the two FMU files are apparently not taken into account. The changes only take effect if I delete the existing FMU block in Simulink, create a new one and load the last FMU I created.
Are the parameters in the FMU block cached somewhere that the FMU block accesses? I have already tried to update the model, but it does not help.Is there any other way, some kind of reset command for the FMU Block, to reload the stored FMU? Since I am planning to automate the simulation, I would like to avoid having to delete the FMU Block and add a new one after each new FMU is created.
Many thanks in advance!Hello everyone,

Issues with SIL Implementation and CCS Integration for AM263P4 using MATLAB Simulink and Embedded Coder
I’m using an AM263P4 control card with MATLAB Simulink (R2024b Update 3) and the Embedded Coder Hardware Support Package for TI AM26x Processors (v24.2.0.12). I can successfully build and deploy to hardware, but unable to import the generated C code into Code Composer Studio (CCS). And the debug option is disabled, and I can’t run or debug for manually added generated code folder to workspace.
To bypass this, I attempted Software-in-the-Loop (SIL) implementation. The build succeeded after updating the build configuration to specify and including GPIO driver paths in Custom Code -> Include Directories. However, during simulation, I encounter undefined reference errors for GPIO functions (e.g., GPIO_setDirMode), suggesting missing or unlinked drivers required for simulation. I tried manually linking libraries, but the issue persists.

FOC PMSM with Hall Sensor Queries
Dear Community,
I am refering https://in.mathworks.com/help/mcb/gs/foc-pmsm-using-hall-sensor-example.html for my motor control application using FOC FOR IPMSM. I am stuck with below queries.
PI Controller: How to decide saturation upper(1) and lower(-1) limits values?
How to decide D-Q Limiter block saturation limit value?
PWM Duty cycle not changing after changing referance speed.
Wrap on overflow error. "Current Control/Input Scaling/Read_Sensor (sim)/Subsystem/Speed Measurement/PositionToCount’
Torque-speed characteristics: For my application V=60V, I=48A,Torque=20Nm. After updating motor parameters, I am not getting expected values on graph.(Attached snapshot for ref.)
mcb_getCharacteristics: Are values shown in graph are in PU_System units or SI units. Please clarify.
Thanks in Advance.
