1. The problem statement, all variables and given/known data I am trying to make a plot of the magnification factor of an underdamped vibrating system versus the frequency ratio using MATLAB. However, my MATLAB skills are very basic and I keep getting an error message. Basically I am trying to plot: MF=1/√((1-r^2)^2+(2ζr)^2) where ζ=0.01 I will be making the plot for other values of ζ later. 2. Relevant equations MF=1/√((1-r^2)^2+(2ζr)^2) where ζ=0.01 3. The attempt at a solution http://img198.imageshack.us/img198/7758/matlabw.png [Broken] *The x-axis will range from 0 to 3.0 After this, I will use the code semilogy(r,MF); to generate the plot. Thanks!
