description: This file explains what data is in the different folders<br>- Frequency response polynomial approximations<br> Contains the frequency response data from the polynomial approximations of the real force The polynomial degree and whether gravity was included or not is in the file names<br> The data contains the following variables:<br> - A: An array of the free magnet peak to peak amplitude at the end of the simulation in the forward direction - P1: An array of the average generated power in the top coil at the end of the simulation - P2: An array of the average generated power in the bottom coil at the end of the simulation - w: An array of the driving anglar frequencies used in the simulation - F_profile A 2D array of the real force profile first koordinate is position and second is force - fit_interval The interval within which the fitting to the real force was carried out - fit The resulting fitting parameters - input A structure of all the values used for the simulation. It corresponds largely to Table 1<br> All variables ending on "_back", means that it was for the backwards (high to low) frequency sweep. The counterparts without the "_back" ending is for the forward (low to high) direction<br><br><br><br><br>- Frequency response real force<br> Contains the frequency response data using the real force Whether gravity was included or not is in the file names<br> The data contains the following variables:<br> - A: An array of the free magnet peak to peak amplitude at the end of the simulation - P1: An array of the average generated power in the top coil at the end of the simulation - P2: An array of the average generated power in the bottom coil at the end of the simulation - w: An array of the driving angular frequencies used in the simulation - F_profile A 2D array of the real force profile first koordinate is position and second is force - input A structure of all the values used for the simulation.

The first index labeled [p/v] can either be 1 for position or 2 for speed<br><br><br><br><br>- Phase diagrams high resolution<br> Contains the data for the high resolution phase diagrams Whether gravity was included or not, is in the file names. <br> The data contains the following variables<br> - A([p],[v]) A matrix of the free magnet peak to peak amplitude at the end of each simulation - P1([p],[v]) A matrix of the average generated power in the top coil at the end of each simulation - P2([p],[v]) A matrix of the average generated power in the bottom coil at the end of each simulation - p An array of the initial positions of the free magnet - v An array of the initial speeds of the free magnet - w The driving angular frequency used for the simulations - Conv([p],[v]) A matrix recording the cycle at which the conversion criteria was passed, and the simulation was ended. 1000 is the max, so simulations with this value did not converge. - Diff([cycle],[p],[v]) A matrix containing the conversion criteria cycle comparisons<br>
