Why does the “goertzel” function not accept arguments in [N, N + 1) as the FFT index for signal inputs of length N in MATLAB R2024a and earlier?

How do I make shaded error bar area instead of lines?
I have data as a neuronal response function listed as my first line of code which is the curve I get. I am trying to add shaded error bars that look similar to this:
My code is:
load(‘0_RF_PSD95-3_20111121-3.CNG.swc_Trials_120_length_2000_p_0.995_a_0.8_beta_0.6.mat’)
SDdiff = std(diff(sort(Fsoma)));
figure; errorbar(h(2:end), diff(mean(Fsoma/500)), …
SDdiff(2:end)/500);
set(gca, ‘XScale’, ‘log’)
and my current figure/output is:

How to sending data from matlab to arduino?

fopen(arduino); % initiate arduino communication
answer = 0.2

PX4 Serial Receive Variable Data Length
Hello,
I am currently trying to receive serial data from a UART&I2C Port in my simulink model. The data stream I am receiving has 6 signals with one singal being an iteration counter that increases from 1 – 1000. This means that the total character length of the serial pack is increasing as time progresses. I have no current way to alter the length of the transmission. When accepting signals that are longer than the prescribed length, valuable data is cut off. When accepting data that is shorter than the prescribed length, erroenous zeros are thrown in to the data making my signals have very jumpy time histories. The only time this system works is when the data is corrent length as specified in the serial receive PX4 block.
Is there a way for the PX4 Serial Receive block to handle a signal with a variable data length?
Furthermore, are there any work arounds with different serial receive blocks that can connect to the relevant ports on a Pixhawk 6x(dev/ttyS4)?Hello,

solving symbolic array to output a numerical solution
Hi there, I was wondering if I could get some feedback on a potential solution for this problem. I am trying to solve for ma3 and obtain a numerical value for each value used in the FLcD3 array. However, the output of Ma3 is a struct with fields. How do I get it so the solution is an array with the numerical values? I’m guessing I would need some form of a for loop but i’m not quite sure how to set it up.
PSW = 0.36:0.03:0.69;

ma3 = sym(‘ma3’, [1 length(PSW)]) ;
eqn1 = (-1./G).*(1-ma3.^-2)+((G+1)./(2.*G)).*log((((G+1)./2).*ma3.^2)./(1+((G-1)./2).*ma3.^2)) == FLcD3;

The output saved in log_file.txt does not match the output when I run the script in Matlab. The output captured in log_file.txt is getting truncated, and I have no idea why. Is there a better way to capture the output than using the -logfile option?

input Matlab table columns to excel formula and perform iteration calculation

And then column2 of meandirection will be input to sheet1.columnF, column2 of meanspeed will be input to sheet2.columnM, results from sheet 3.columnP will be saved.

OPA Gatekeeper Bypass Reveals Risks in Kubernetes Policy Engines
Implementing Kubernetes securely can be a daunting task. Fortunately, there are tools in the K8s toolshed that provide out-of-the-box solutions using a single click. One such tools is OPA Gatekeeper. It is a great out-of-the-box security checkpoint to enforce security policies on Kubernetes. But are users using it correctly? Do they understand its limitations? Our new research says not necessarily!

time lag where the phase of the signals is not consistent
I have two time series where I have used xcorr to calculate the lag between two signals. However, I am sure that the time lag will not be consistently over the course of the time series. Is there a way to do a moving window time lag or another way to compute how this lag varies through time?

O1 = TO(:,2);
S1 = TO(:,3);

Interact with Heatmap embedded in a scrollable UI Panel
I knew how we can click into a Heatmap cell and get its row and column info. This can be done by comparing the mouse-clicking position vs the Heatmap position. But what if my Heatmap has many rows such that when it is created inside a UI panel, the panel becomes scrollable, say the mouse position when I click row 2 is the same as the position when I scroll down and click row 22? Is there a way to get the correct row and column index when I click on a cell after scrolling down?
I’m currently using the "heatmap" function to generate the heatmap. But if above can only be realized using other methods when creating heatmap, feel free to suggest (though my preferred way is to use the "heatmap" function as it gives better flexibility and functionality with the actual heatmap)I knew how we can click into a Heatmap cell and get its row and column info.
