Vectorisation: Colon operator with floating point increment error

Hi,

For y=400:1.6:1200; Expected output is =400, 401.6,...1198.4,1200.

But Matlab gives output in the form: 1.0e+03 *Columns 1 through 11 0.4000 0.4016 0.4032 ...1.200.

Can you advise how to get the expected output. If it has already been addressed, kindly share the link to look through.

Thanks!

[Manu M]

y=400:1.6:1200;

z=round(y);

What?? did you inspect the values first?? You ask in the question that you want the second element to be 401.6 whereas after round you get 402, are you aware of it?? If latter was the desired result then wouldn't be simpler to use:

y = 400:2:1200 % ??

Give the command

format long g

and then display the data again.
