 v2 ==  Function: == As for [https://www.meteo.unican.es/trac/meteo/wiki/SpecsEuporias/Interfaces/RPackage/Python Phyton], a ''Matlab'' function ([https://www.meteo.unican.es/trac/MLToolbox/browser/MLToolbox/trunk/MLToolbox_experiments/antonio/system4/matlab/loadSystem4.m loadSystem4.m]) has been created in order to access the ''SPECS-EUPORIAS Data Portal'' in a user-friendly way. The ''loadSystem4'' function is called this way: As for [https://www.meteo.unican.es/trac/meteo/wiki/SpecsEuporias/Interfaces/RPackage/Python Phyton], a ''Matlab'' function ([https://www.meteo.unican.es/trac/MLToolbox/browser/MLToolbox/trunk/MLToolbox_experiments/antonio/system4/matlab/loadSystem4.m loadSystem4.m]) has been created in order to access the hindcast of the System4 stored in the ''SPECS-EUPORIAS Data Portal'' in a user-friendly way. This would be a typical call to the function: {{{ The input arguments are next described: * dataset: A character string indicating the full URL path to the OPeNDAP dataset. Currently, the accepted values correspond to the System4 datasets described in Section [https://www.meteo.unican.es/trac/meteo/wiki/SpecsEuporias/DataServer/Datasets Available Datasets]. * var: Variable code. Argument values currently accepted are tas, tasmin, tasmax, pr or mslp, as internally defined in the vocabulary for System4 following the nomenclature displayed in the table below. However, note that new variables and datasets will be progressively included. * season: A cell of two strings indicating the first and final months of analysis. A single month can be specified (as in the above example) or a standard season (e.g. season = [12,1,2] for standard Boreal winter, DJF). * leadMonth: Lead time (in months) to consider. For instance, leadMonth = 1 for January forecasts means considering the initialization of the first of December. * members: Vector with the list of members to select. * xlim: Vector of length = 2, with minimum and maximum longitude coordinates, in decimal degrees, of the bounding box selected. * ylim: Vector of length = 2, with minimum and maximum latitude coordinates, in decimal degrees, of the bounding box selected. * dataset: A string indicating the full URL path to the OPeNDAP dataset (see [https://www.meteo.unican.es/trac/meteo/wiki/SpecsEuporias/DataServer/Datasets Available Datasets] to check the catalog of available datasets). * var: Variable code. Values currently accepted are tas, tasmin, tasmax, pr or mslp. However, note that new variables and datasets will be progressively included. * season: A cell of two strings indicating the first and final months of analysis. A single month ({'Jan';'Jan'}) or a standard season ({'Dec';'Feb'}) can be specified. Note that months are indicated by their three first letters. * leadMonth: Lead time (in months) to consider. For instance, leadMonth = 1 for January forecasts means considering the initialization of the first of December . * members: Vector of length ''n'' indicating the ''n'' members to consider. * xlim: Vector of length = 2 with minimum and maximum longitude coordinates (in decimal degrees) of the bounding box selected. * ylim: Vector of length = 2 with minimum and maximum latitude coordinates (in decimal degrees) of the bounding box selected. * user: Username for accessing the OPeNPAD dataset. * passwork: Password for accessing the OPeNPAD dataset. * password: Password for accessing the OPeNPAD dataset. These are the arguments returned by the function: * lat: Vector with the latitudes of the selected domain. * lon: Vector with the longitudes of the selected domain. ==  Example: ==
