That depends. Your question is too generic. What are you trying to do? Curve fitting? And also you haven't told us what is the expected output yet. If you only want to draw the text inside an image, that would be easy. You could do that with
and similar packages. If you want to present output as plain text, then you need to add <pre> and </pre> tags around your output to preserve the returns. But the solution depends on your actual problem.
So one step at a time. Please give more detail on the problem.
