Unformatted text preview: 4 BRETSCHNEIDER SPECTRUM DEFINITION 4 Bretschneider Spectrum Definition The formula for the Bretschneider (one-sided) ocean wave spectrum is 5 S ( ω ) = ω 4 m 16 4 H 2 5 5 1 / 3 e- ω m / 4 ω 4 ω where ω is frequency in radians per second, ω m is the modal (most likely) frequency given wave, and H 1 / 3 is the significant wave height. Make a single figure that sho Bretschneider spectrum ( S as a function of ω ) for these cases: SeaState 2 π/ω m , sec H 1 / 3 , m 2 6.3 0.3 3 7.5 0.9 4 8.8 1.9 5 9.7 3.3 6 12.4 5.0 Here is the MATLAB code I used and the resulting figure: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % 2.017 Homework 1.
