Is there a built in method that formats the output of a matrix to not automatically use scientific notation? Even though I've used format long, it still automatically decides to use scientific notation regardless. See the image.

What makes this annoying is that when I output the data matrix, the matrix has more than 100 rows. So I don't see that "1.0e+04" at the top and I think the data/math is wrong until I scroll up.
