Matlab command line output

What does this imply? what does the asterisk sign mean? I don't understand what 1.0e+13* signify. Please explain

Answer 1

[Chunru]

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.
