"I want just use 0.2 and 0.2, I don t need zeros after "
Floating point number types do not store formatting information (like how many trailing/leading zeros are displayed).
I suspect that you are mixing up how data are displayed, with what data are stored in memory. Changing how many zeros are displayed makes absolutely no difference to the numeric data stored in memory.
Question: what are you planning on doing with these values? Then we can discuss approriate approaches.

A wild guess:
V = [0.2,0.2862]
W = fix(V*10)/10

"but I need also to remove these zeros the results that I want is 0.2 and 0.2"
Then you need to first answer my question here:
It is certainly possible to display numeric values with a certain number of fractional zeros, or select the number of fractional zeros when converting to text:
N = 0.2
S = sprintf('%.1f',N)
But so far you have not made it clear if text is what you require.
