Set of Matlab(r) functions for the partition of directional wave spectra to its wind and different swell components. The partitions are initially identified using a watershed defining algorithm and then are modified following mostly the method described in Hanson and Phillips (2001).

Code Updates:

• 1/22/2020 - waveparams.m - the mean freq. (fm) estimate was incorrect; it has been corrected.
• 1/22/2020 - partition.m was updated to catch cases when a flat spectrum is given as input.
• 1/22/2020 - master_partition.m was updated so that it calls waveparams.m with the correct number of outputs.
• 1/21/2020 - waveparams.m - the Hrms estimate was incorrect; also the mean direction now is given in -180 to +180 deg range.
