It means the scale factor for the following numbers. You can consider * as multiplication. For example.

a = randn(1,4)*1e6
a = 1×4
	1.0e+06 *

   -0.6917    0.2892   -1.7645    0.2282

Here a is 1.0e+06 * [-0.6917, 0.2892, ...]

I recommend that you use

format long g

in order to see the real output.

I also recommend that you change your MATLAB preferences to use long g for the command window and for the variable browser.
