Hi, I want to ask a question I want a program where I can add more row data every time I execute this program, but when i execute this code, only row 2 got added, not 3, 4, etc. I want it to stack, every time I run the program
here is the code :
tgl=4;
Jumlah=1;
nama='adawd';
ntgl=3;
nJumlah=3;
nnama='dddd';
A = {'Tanggal','Jumlah Laki-Laki','Nama Video'; tgl,Jumlah,nama};
baru = {ntgl,nJumlah,nnama};
A(end+1,:) = baru;
xlswrite('Masukkan nama file.xls',A);

You need to use the xlsread() first to determine what the last row of your existing data it. Then use xlswrite's 3rd and 4th arguments to make sure you're writing additional data to the end of the existing data.

ok, if i have different set of data to write into excel file like this:
data1= [0.1, 0.2, 0.3, 0.4];
data2= [0.5, 0.6, 0.7, 0.8];
data3=[0.9, 0.10, 0.11, 0.12];
the question is:
1-how to write it to the excel file with different set of data?
2-after close the application and run again, how to append the new set of data into the existing excel file without missing the existing data in the file?
tqvm for your response.

One way to do it would be to first read it in and see what the last row is. Then write to the row below it.
[numbers, strings, raw] = xlsread(filename);
lastRow = size(raw, 1);
nextRow = lastRow + 1;
cellReference = sprintf('A%d', nextRow);
xlswrite(excelFullFileName, data1, 'Sheet1', cellReference);
nextRow = nextRow + 1;
cellReference = sprintf('A%d', nextRow);
xlswrite(excelFullFileName, data2, 'Sheet1', cellReference);
nextRow = nextRow + 1;
cellReference = sprintf('A%d', nextRow);
xlswrite(excelFullFileName, data3, 'Sheet1', cellReference);

Check this code. It may help to write and append data in an existing Excel sheet:
A=magic(5);
header={'Hazem', 'Gigi', 'Rita', 'Karim', 'Viola'}
xlswrite('test.xlsx',header);
[number, strings, row] = xlsread('test.xlsx');
lastRow = size(row,1)
nextRow = lastRow+1;
cellReference = sprintf('A%d', nextRow);
xlswrite('test.xlsx', A, 'Sheet1', cellReference);
winopen('test.xlsx');
