You can use the ExportMatrix command with the followingsyntax.ExportMatrix( "filename", data )Here, filename is the string containing the name of the file to whichExportMatrix writes the data, and data is a Matrix. Note that any list,vector, list of lists, or table-based matrix can be converted to a Matrix byusing the Matrix constructor.
