writing a data in notepad without overwriting it

hi

lets assume there is a for loop

for i=1:1:10

csvwrite('num.dat',i)

end

when i open the num.dat file there is only the data 10 in it where as i am suppose to store 1,2,.....10 ..suggest me an efficient way for it .. if the text pads are complicated ones to write this array suggest me to write the datas in the xls sheet ..that too will be sufficient ....

I make your program a little change and it works.But I don't know if it is what you required!

for i=1:1:10

j(i)=i;

csvwrite('num.dat',j)

end

CSVWRITE does not append the new data, but overwrites the former values. Therefore you should use the complete vector as input:

csvwrite('num.dat', 1:10);
