copy from workspace to csv file without loss of significant figures

Hello,

I am trying to copy an array to excell using the csvwite function. It works very good and fast, BUT I am losing a lot of significant figures. I only keep 5 of them. This means a significant loss of data for my solution. I tried ctrl+C but matlab fails (stops working, have to restart matlab) It is a rather big array of 30.000+ values (double) Is there a way to copy it to a file without losing the data?

Dries, how about using dlmwrite?

 data = rand(3000,10);
 dlmwrite('test.csv',data,'precision',15);

This works! Thank you very much!

But it only writes the first 3500 words... How is this possible?

When you say words, do you mean strings (and not doubles)? What happens when you execute the code from my answer?
