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);
