Can anyone explain this output?

entering a matrix x=[3;9;4;5;2] then doing y=exp(x)

returns result of

1.0e+03 * <----- why this line?

0.0201 8.1031 0.0546 etc....

all of the values are correct but off by a factor of 3 (obviously from the first line)

I run this on another machine and DO NOT get "1.0e+03" as my first returned line and the answers come out correctly - the prefs are the same for both machines - but why the difference?

It's just because of the way the data is formatted for display.

 doc format

Set the same format in the two machines if you want them to give the same display, e.g.:

 format long

And that line is the multiplier;

 exp(3) = 0.0201 * 1.0e+3 = 0.0201 * 1000 = 20.1
