78 Chapter 4 LAY-OUT [idla] unstructured grids. Some MATLAB scripts are provided with the SWAN source code that can be used to plot wave parameters as maps in a quick manner. with this option the user can prescribe the lay-out of the output to file with the value of [idla]. see command READINP (options are: [idla]=1, 3, 4). Option 4 is recommended for postprocessing by MATLAB, however, in case of a generated binary MATLAB file option 3 is recommended. Default: [idla] = 1. ONLY MEANT FOR STRUCTURED GRIDS. For definitions of the output quantities, see Appendix A. Note that the wave parameters in the output of SWAN are computed from the wave spectrum over the prognostic part of the spectrum with the diagnostic tail added. Their value may therefore deviate slightly from values computed by the user from the output spectrum of SWAN which does not contain the diagnostic tail.
