Given: A Matlab data set and basic script is provided with velocity data from a panel excited in the center at 800 Hz. An example code of a 1D wavenumber transform is provided.
To review: Given a 1D velocity response, vel, and the position vector, x, with spacing dx, the velocity response can be converted to the wavenumber domain. The following equations can be used to compute the wavenumber axis.
Number of Points: Nx=Length(x)
Total Measurement Length: Lx=Nx*dx
Wavenumber Sampling Frequency_Ks=
