Hi,

I'm trying to loop through this code 3 times and save the variable states to the excel file. I want to name the excel files 1.xls, 2.xls and 3.xls.

Could anybody tell me what I am doing wrong with the xlswrite as it is not working. Thank you.

for j=1:3 transC = [zeros(size(T,1),1), cumsum(T,2)]; %cumulative sum of rows, we will use this to decide on the next step. n = 10000; states = zeros(1,n); %storage of states states(1) = 32; %start at state 1 (or whatever) for ii = 2:n %Generate a random number and figure out where it falls in the cumulative sum of that state's trasition matrix row [~,states(ii)] = histc(rand,transC(states(ii-1),:)); end xlswrite('C:\j.xls',[states],'Sheet1', 'A2'); end

Accepted answer

You need to construct the filename properly. Replace this:

xlswrite('C:\j.xls',[states],'Sheet1', 'A2');

with this:

baseFileName = sprintf('%d.xls', j); fullExcelFileName = fullfile(yourFolder, baseFileName); % yourFolder can be pwd if you want. xlswrite(fullExcelFileName ,[states],'Sheet1', 'A2');

We're waiting for you to tell us what the outcome of the code is.
