最多支援26*26列資料記錄；

在**後面增加新資料。

測試程式

%寫資料到excel**


filename = ['./data/udp_truestates-',datestr(now,30),'.xls'];


v = [1 2 3];


p = [4 5 6];


headers = ;


num_length = length(headers);% 定義**的列數，**的列數與headers的長度相同


xls_row = num2str(1);


xls_colume_start = 'a'; %初始列。'a'表示從**的第一列開始寫起


%計算最後一列。excel列的命名方式是：a-z,ba-bz,...,za,-zz


%所以這裡最多支援26*26列


if rem(num_length,26) == 0 


xls_colume_end = char('a' + mod(num_length,26) - 1);


else


colume_26 = rem(num_length,26);


xls_colume_first = char('a' + colume_26);


xls_colume_second = char('a' + mod(num_length,26) - 1);


xls_colume_end = [xls_colume_first, xls_colume_second];


endstart_point= [xls_colume_start, xls_row];


end_point = [xls_colume_end, xls_row];


xlrange = [start_point,':',end_point];


data = headers;


if length(data) < num_length


data = [data,zeros(1, num_length - length(data))];


endxlswrite(filename, data,xlrange);


for i = 1:10


xls_row = num2str(i+1); %更新行


data = ones(1,5)*i;


my_xlswrite(filename, xls_row, xls_colume_start, xls_colume_end, data, num_length)


endfunction my_xlswrite(filename, xls_row, xls_colume_start, xls_colume_end, data, norm_length)


start_point= [xls_colume_start, xls_row];


end_point = [xls_colume_end, xls_row];


xlrange = [start_point,':',end_point]; %更新寫入excel中的範圍


if length(data) < norm_length %給定的資料少於**的列數，少的資料用0補齊


data = [data,zeros(1, norm_length - length(data))];


endxlswrite(filename, data, xlrange);


end
