Hello, Below is my code that would write data into a text file.
fileID = fopen('G:\FLOW_OUT_32.txt','w');
formatSpec = '%d %2.5f \n';
[nrows,ncols] = size(output32);
for row = 1:nrows
fprintf(fileID,formatSpec,output32{row,:});
end
fclose(fileID);
I would like the data to be written in the format shown below. Any help would be appreciated. Thanks

You shouldn't need a loop.
fileID = fopen('G:\FLOW_OUT_32.txt','w');
fprintf(fileID,'%d %12.6e\n',output32.'); %assuming out32 is a nx2 matrix
fclose(fileID);
