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.
