Details:

The following creates a corrupted file:


fid=xlsopen("file.xlsx", 1, "OCT");
[fid,stat] = oct2xls(1*ones(3),fid,"a")
[fid,stat] = oct2xls(2*ones(3),fid,"b")
[fid,stat] = oct2xls(3*ones(3),fid,"c")
fid=xlsclose(fid)


A simple workaround consist in first creating the file and than adding more
worksheets:


xlswrite("file.xlsx",1*ones(3),"a");

fid=xlsopen("file.xlsx", 1, "OCT");
[fid,stat] = oct2xls(2*ones(3),fid,"b")
[fid,stat] = oct2xls(3*ones(3),fid,"c")
fid=xlsclose(fid)
