It writes map struct to files in SOM_PAK format. See SOM_READ_COD for description of the SOM_PAK map file format. Because the SOM_PAK package does not support many of the features and options of the SOM Toolbox, some of the information is changed, or even lost. SOM_PAK does not support 3- or higher dimensional map grids. These cannot be exported using this function. SOM_PAK always supposes that the map has 'sheet' shape. SOM_PAK only supports 'bubble' and 'gaussian' neighborhood functions. Any other neighborhood function is changed to 'gaussian'. SOM_PAK doesn't support component names. However, the component names are written on a comment line which begins with '#n '. Any spaces (' ') in the component names are replaced with underscores ('_'). Information on map name, mask, training history and normalizations is lost. This function is only offered for compatibility with SOM_PAK. In general, when saving map structs in files, use 'save filename.mat sMap'. This is faster and retains all information of the map.</PRE><H3> Required input arguments </H3><PRE> sMap (struct) the SOM struct to be written filename (string) the name of the input file</PRE><H3> Examples </H3><PRE> som_write_cod(sMap,'map1.cod');</PRE><H3> See also </H3><TABLE NOBORDER WIDTH=80%><TR><TD><a href="som_read_cod.html"><B>som_read_cod</B></a><TD> Read a map from a file in SOM_PAK format.<TR><TD><a href="som_read_data.html"><B>som_read_data</B></a><TD> Reads data from an ascii file.<TR><TD><a href="som_write_data.html"><B>som_write_data</B></a><TD> Writes data struct into a file in SOM_PAK format.</TABLE><p><hr><br><br><!-- Last updated: May 30 2002 --></body></html>?? 快捷鍵說明
