Using symbolic solver, I seem to not be able to get a system of equations that give me a desired answer. Does a solution not exist?

So I am trying to find values for Rn,Rx and Rp. I have three equations and three unknowns. When I use solve to find symbolic equation, I get equations for each variable. But when I sub real values in, I get an answer that is wrong or doesnt make sense. Adding assume doesnt seem to change anything and the return conditions is the same as the equations. The real values of Rn, Rp and Rx should be 2e6,1.5e6 and 700k. If you were to put these values in the original equations, you can verify that these values are correct.

filtfilt provides excessive transient
I observed that ‘filtfilt’ suffers from an undesired behavior when I provide IIR bandpass filters having steep transition bands. Specifically, the output signal exhibits excessive transient response; nevertheless, this behaviour does not emerge if I use a ‘home-made’ version of zerophase filtering based on ‘filter’. I guess that it is not a numerical issue involving the filter coefficients or structure, nor the ‘filter’ function.
% design bandpass filter having transition bandwidth of 200 Hz (Fs = 8000)
bp = designfilt(‘bandpassiir’, ‘StopbandFrequency1’, 50, ‘PassbandFrequency1’, 250,…
‘PassbandFrequency2’, 3600, ‘StopbandFrequency2’, 3700, ‘StopbandAttenuation1’, 30,…
‘PassbandRipple’, 0.1, ‘StopbandAttenuation2’, 30, ‘SampleRate’, 8000, ‘DesignMethod’, ‘cheby2’);
% check stability
assert(isstable(bp),’Unstable filter’);
% apply filtfilt to a random (white) long input signal; output signal shows an undesirable transient
x = randn(2^20,1);
y = filtfilt(bp,x);
% apply ‘home-made’ filtfilt to the same input; output signal shows a more accptable transient
y2 = flipud(filter(bp,flipud(filter(bp,x))));
% compare effects
figure; semilogy(abs(y-y2));
As a rule of thumb, the effect grows as the transition bands get narrower, while it tends to vanish as they get broader.

Reading Bytes from Arduino to MATLAB
I’ve been trying to read data from ESP32S-Dev module to MATLAB sending over the data in bytes to make the transmission quicker. As seen below, I convert float data into bytes and then write the data. MATLAB sees the data and then creates a 1×8 array for each float value instead of just 1 value for each float. I’ve tried other methods, shown in 2nd part of MATLAB code, and it creates 1 value for each float but their wildly off (7-34 orders of magnitude)
I’ve tried different baud rates and even asked for help from the almighty ChatGPT but have not been able to crack the code. Any thoughts.
Arduino IDE code:
#include <SPI.h>
const int CS_SiPM_pot = 34;
void setup() {
// put your setup code here, to run once:
Serial.begin(115200); //Starting
delay(1000);
SPI.begin();
pinMode(CS_SiPM_pot, OUTPUT);
}
void loop() {
for (int d_pot2 = 55; d_pot2 <= 55; d_pot2 = d_pot2 + 1) //57
{
digitalWrite(CS_SiPM_pot, LOW); //LOW
delay(10); //10
SPI.transfer(d_pot2);
digitalWrite(CS_SiPM_pot, HIGH);

float newTmp[4] = { 01.00, 02.00, 03.00, 04.00 };
for (int i = 0; i < 4; i++) {
byte *byteData = (byte *)&newTmp[i];
Serial.write(byteData, sizeof(float)); // Send each float as 4 bytes
delay(10);

When the orientation of the object changed, how to measure the force on each support point?
Thank you for your interest in my question.
If we assume that there is a box with x, y, z-axis lengths of [1, 0.5, 0.2] (m) , weight is m=100kg,
and set the center point as the origin frame. At this time, if we support the force of m*g/4 at each of the four points [0.5, 0.25, -0.1], [0.5, -0.25, -0.1], [-0.5, -0.25, -0.1], [-0.5, 0.25, -0.1], the object will stay statically.
Then, if the box rotates 30 degrees about the x-axis, I can’t measure the force applied at the four corners of the box.
As the box rotates, the coordinate frame of the corner also rotates.
If the box rotates 45 degrees for y-axis after rotating 30 degree for the x-axis,
how should we apply force to each point so that the box stays still?Thank you for your interest in my question.

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.

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:

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.

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,

Confirming a confirmed track for GNN tracker

After gettting the confirmed tracks, I would like to check make another check with some detections and then keep the old track alive. How can I achieve this? I saw that there is a trackStateLogic which is appended with a zero everytime a track does not get a detection. But I was uable to change it for a confirmed track.

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:
