Hi,
you can define sheet name on the xlswrite function.
xlswrite(filename, M, sheet)
I can imagine that you can put the integer as (a part of) sheet name
add
warning off MATLAB:xlswrite:AddSheet
to supress addsheet warning
HTH,
IH

hi, thanks for your reply, i don't want to add the sheet number manually every time, i want it to happen in the loop . i am providing the code below
for i=1:1:24
fname='figure';
ext='.png';
fnamer=sprintf('%s %d%s',fname,i,ext);
I=imread(fnamer);
a=rgb2gray(I);
end
% i want to perform some mathematical operations on matrix 'a' , which gives me an output of 13x1 matrix and i want to save this in sheet1 in a excel file. when i value increments to 2 again it will give me a 13x1 matrix as output and i want to save this in sheet2 of the same excel file and as the loop progress i want it to save in the appending sheets.
thank you .
