### How to plot this data set, ignoring the initial oscillation?

We may change the duplicated points by the mean of their neighbors. This gets complicated because the duplicated points are not exactly equal. Therefore, we must first determine the positions of the ...

### Fitting Eigenvalues of a 8*8 matrix to experimental data

You may fit the eigenvalues of an 8x8 parameterized matrix to your experimental data by defining a function that computes the eigenvalues based on given parameter values. Then, define a cost function ...

### Fitting a time domain function to frequency domain experimental data

I agree with @A. Kato in the comments that there is no good fit under your assumptions about the function. I wrote some code to perform the fitting, where the loss used is the relative error of the ...
