How to smoothen the noisy part of the data?. Learn more about data filtering, butter, matlab, datasmoothing, movmedian, signal processing MATLAB
The 3rd plot is a comparison: when data's not noisy, Matlab produces a flat background part (the blue part) too. I wonder if there's anyway I can get do the same as in Origin using Matlab. Or do I have to smooth the data myself?
The code below displays a smooth function and my attempt to estimate it from random samples using nufftn(). The range and overall shape of the estimate comes out right on, but it's very noisy, becaue the random samples aren't uniform and therefore aren't great for estimating Fourier ...
In a previous article I introduced the Whittaker-Eilers smoother¹ asThe Perfect Way to Smooth Your Noisy Data. In a few lines of code, the method provides quick and reliable smoothing with inbuilt interpolation that can handle large stretches of missing data. Furthermore, just a single parame...
How close to a true sine wave is the output signal? Perhaps you could post images of the fft of the desired output signal, and the fft of the noisy version of it ? http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers ...

what I am trying to figure out is how to basically pad the data so that it begins after the artifact created by the filtering - I just want to start the analysis a couple of seconds forward from the data...Some
Open in MATLAB Online data.mat test3.m I plotted the data then it looked like the squirrely stuff stopped around element 2300 or so, and started to get fairly linear after that. So I found the slopes from element 2300 to the end of the data and plotted it. ...
