Mo'men,
Check out the round function.
r_rounded = round(r,2); % rounds to 2 decimal places
Hope this helps.

Thanks for the mega-fast answer!
In principle I wanted to copy the matrices from the Variables window in MATLAB. I tried to copy them from the command window with the short g format, as you suggest, but then it is like copying a bunch of text and I don't manage that it gets pasted correctly in the table.
What do you mean with the COM stuff in Word?
Thanks

You can write to word with the report generator function. I used this for rounding a table to go into this:
M = round(V*100)/100;
C = num2cell(V);
fun = @(x) sprintf('%0.2f', x);
V = cellfun(fun, C, 'UniformOutput',0);
V=array2table(V);
