How to export data from Matlab to excel for a loop?

Question

I have a code for \"for loop\"

for i=1:4 statement... y=sim(net, I); end

now

Answer 1

You can store sim outputs in a vector (y(ii)) and save in the sheet with a single write. This is also more efficient since you perform a single bulk-write instead of many small writes.

Specify the first cell and y will be written starting from there.

last = someNumber;
for i=1:last statement... y(i)=sim(net, I); end

xlswrite('output_data.xls', y', 'output_data', 'A1');

If you prefer specify the range write ['A1:A',num2str(last)] instead of A1.

If you really want to write within the loop try:

for ii=1:last
    ...
    y=sim(net, I);
    xlswrite('output_data.xls', y, 'output_data', sprintf('A%d',ii));
end
