Example — Writing To an XLS File. This example writes a mix of text and
numeric data to the file tempdata.xls. Callxlswrite, specifying a worksheet
labeled Temperatures, and the region within the worksheet to write the data
to. The 4-by-2 matrix is written to the rectangular region that starts at cell E1
in its upper-left corner:
d = {'Time', 'Temp'; 12 98; 13 99; 14 97}
d =
'Time' 'Temp'
[ 12] [ 98]
[ 13] [ 99]
[ 14] [ 97]
xlswrite('tempdata.xls', d, 'Temperatures', 'E1');
6-98
