Include rows containing specific value
I have a 1400*9 table (1400 rows and 9 columns) in MATLAB workspace. Each column has a different name. I want to select rows containing specific value. For example, how can I create a new table containig all rows with value of 0.456 in the column named "Biology"? I tried to use following code, but it gave error.

Force saved figure to use a specific number of pixels
I am saving different maps, I need to compare some specific pixels, but Matlab somehow adds a line at the bottom (3 pixels) for example when I save my image, which kills everything I try to do later. Is there any method to force exportgraphics to use X pixels horizontally and Y vertically (I mean height and width)? Or when I call my figure to be X and Y dimensions? Force it not to add this line. I tried exportgraphics/export_fig they both fail at it.
It is not random, as only some specific files get the line added and always even if I try to replot, I still did not figure out why this happens, my data have the same resolution/grid.I am saving different maps, I need to compare some specific pixels, but Matlab somehow adds a line at the bottom (3 pixels) for example when I save my image, which kills everything I try to do later.

Working in Excel with live on MATLAB
On matlab, I am going to import an Excel file and work on it live in real time.
If I change the value in Excel, I want to reflect it in real time in MATLAB.
However, as far as I know, if you modify it without saving the Excel, it cannot be applied in MATLAB right away.

Logging cmd in multiple diary
Hi,
i’m facing an issue in logging using the matlab ‘diary’ functionality. In the below pseudo-code i have 2 tools and both use diary to log the command window output and one is calling other. The diary off for 2nd tool is terminating the diary for the 1st tool as well due to which the remaining cmd display is not getting logged anywhere.
Here is how the logs are:
Is there a way to use ‘diary’ or some other functionality that would help is logging the command window output for the beow example ?

Select the type of cosimulation you want to do. If the HDL simulator executable you want to use is not on the system path in your environment, you must specify its location.
——————– Step 2——————
Add all VHDL, Verilog, and/or script files to be used in cosimulation to the following table. If the file type cannot be automatically detected or the detection result is incorrect, specify the correct file type in the table. If possible, we will determine the compilation order automatically using HDL simulator provided functionality. Then the HDL files can be added in any order.
——————– Step 3——————
HDL Verifier has automatically generated the following HDL compilation commands. You can customize these commands with optional parameters as specified in the HDL simulator documentation but they are sufficient as shown to compile your HDL code for cosimulation. The HDL files will be compiled when you click Next.

Select the type of cosimulation you want to do. If the HDL simulator executable you want to use is not on the system path in your environment, you must specify its location.
——————– Step 2——————
Add all VHDL, Verilog, and/or script files to be used in cosimulation to the following table. If the file type cannot be automatically detected or the detection result is incorrect, specify the correct file type in the table. If possible, we will determine the compilation order automatically using HDL simulator provided functionality. Then the HDL files can be added in any order.
——————– Step 3——————
HDL Verifier has automatically generated the following HDL compilation commands. You can customize these commands with optional parameters as specified in the HDL simulator documentation but they are sufficient as shown to compile your HDL code for cosimulation. The HDL files will be compiled when you click Next.

MATLAB standalone app installation without administrator
Hi,
I am trying to make some MATLAB apps for people without MATLAB licenses at work. I compiled them as standalone apps with the runtime libraries included in the package so they don’t have to be downloaded and installed separately. However, the app requires admin privileges to install. This isn’t very pleasant since we have to request IT for each installation.
Is there a way to eliminate the need for administrator privileges? I tried moving the installation directory to the user directory instead of Program Files but that didn’t help as well.
Thanks,

Efficient Code for Filling Rows of an Array involving Indices Ranges
Hello,
I have an array A of zeros. I need to set a range of column indices for each row of A to ones. These ranges are determined by elements of another vector B, specifying start and end indices for the ranges for each row. For example, this is what I’m trying to figure out:
<</matlabcentral/answers/uploaded_files/18907/matrixA.jpg>>
<</matlabcentral/answers/uploaded_files/18908/matrixB.jpg>>
<</matlabcentral/answers/uploaded_files/18909/matrixA2.jpg>>
The first row of B indicates that the first row of A should have ones from columns 1 to 3. The second row of B indicates that the second row of A should have ones from columns 2 to 4 etc.
I could code this with a for-loop that goes through each of the rows and creates indices with the colon operator however, I’m hoping for a smarter, more efficient way to do it than that.
Can anyone help me with this or any suggestions?

How do I incorporate a feedforward control signal into an MPC block?
I have designed a feedback control system using an Model Predictive Controller block for a DC Motor servomechanism. In order to reduce the steady-state error I want to include a feedforward control signal that I can estimate and predict. The MPC block therefore needs to have knowledge of the feedforward control signal as, I assume, a measured disturbance which is able to be previewed. I have implemented this as below:
I haven’t been able to improve the controller performance with this architecture as I would expect (previous PI + Feedforward works very well), so I wanted to ask whether this was the correct approach to include the feedforward signal into the MPC block?I have designed a feedback control system using an Model Predictive Controller block for a DC Motor servomechanism.

Need help to removing motion (breathing?) artifact from ECG signal
I have this single-channel ECG signal with motion artifacts (I believe from breathing).
I’ve tried several filters, but none have given me a good output.
Not being an expert, I followed the instructions from Kher, 2019 with this code, but a compatibility issue (since I am using version 2018b) prevents me from obtaining any results; by changing some commands the result is unsuitable:
y1 = load(‘EKG.mat’);
y2= (y1 (:,1)); % ECG signal data
a1= (y1 (:,1)); % accelerometer x-axis data
a2= (y1 (:,1)); % accelerometer y-axis data

a = a/max(a);

Hd = dsp.LMSFilter(‘Length’, 32, ‘StepSize’, mu);

I tried multiple lsqcurvefit, which means the below process. But, it needs so many hours….
calculate the x by lsqcurvefit and have the loop number. e.g. loop number = 100
set MaxIterations as 10 and calculate the x10 by lsqcurvefit
set MaxIterations as 20, 30,,,,100 and calculate the x20, x30,,,x100, respectivelly by lsqcurvefit
make the graphs with x10,x20,,,x100 lsqcurvefit, middle data, plot MATLAB Answers — New Questions
MATLAB Plots *.tif According to Light
Hi,
I am trying to plot a lunar terrain from a *.stl file. You can see the real image and plot in photos. MATLAB is plotting the deepest place as dark blue, the highest as yellow, but the thing is MATLAB’s dark blue is not actually the deepest place, it is just shadow, likewise MATLAB’s yellow actually isn’t the highest place, it just takes the most light so its brighter. This is my code snippet to plot it. My real aim is to create a simulation, therefore I need the surface model.
[dem, ~] = readgeoraster(‘moon1m-a.tif’);
gridSize = 3900;
start = 1;
[X, Y] = meshgrid(1:gridSize, 1:gridSize);
Z = dem(start:start+gridSize-1, start+gridSize-1:-1:start);
figure
mesh(X, Y, Z);
Images are aligned, you can see the shadow places at the bottom right.
I can’t put the file into the attachments, it is too big even after compressing. I can put the *.tif into a 3D drawing tool, this is the output.
Any help would be appreciated.
Thanks in advance.Hi,

Mimic axis equal in secondary y-axis
Is there a way to mimc ‘axis equal’ for a secondary axis? ‘Axis equal’ doesn’t work when using yyaxis(ax,’right’).
In addtion, the mimic should resize the same as if ‘axis equal’ was called on a single plot.Is there a way to mimc ‘axis equal’ for a secondary axis? ‘Axis equal’ doesn’t work when using yyaxis(ax,’right’).
