Hi, i have a variable like this:
Velocity = 6.76979593929292939392
And I want it to round it to this:
Velocity = 6.80
So, just one number behind the period. I have tried round(Velocity,1) but it did not work.
Thanks!

Since R2014b, round accepts a number of digits to round to:
Velocity = round(Velocity, 1);
In older versions of matlab, you have to use Azzi's answer.
