% Directory of chapter 7 toolbox codes.

% VTB7_1 is an example of finding a power spectral density
% of data. The power spectral density of a signal
% containing .5 Hz and 1.59 Hz signals is plotted.
% VTB7_2 generates the discrete frequency response
% function (H(iw)) between two signals.
% VTB7_2EX VTB7_2EX.MAT is an example data file for VTB7_2.
% VTB7_3 A set of files numbered from VTB7_3_1.MAT to
% VTB7_3_6.MAT exist which contain discrete frequency
% response functions. After loading the data,
% plot(FreqV,abs(Xfer)) will give the magnitude,
% plot(FreqV,angle(Xfer)) will give the phase
% plot, and plot(Xfer) will give the Nyquist plot.
% Note the differences between experimental
% data and what you would expect from theory.
% VTB7_4 Curve fit to a FRF. Used in modal analysis
% VTB7_5 Frequency Response Function from second order system matrices.
% VTB7_6 Matrix iteration + deflation solution of large eigenvalue
% problems.
