How do I remove trailing zeros after rounding a matrix while retaining current rows/columns format?

I am trying to display a matrix that with numbers all rounded off to 1 decimal point. Currently when I round, there is a 0 that remains in the hundreths place of each number. I'd like to remove this last zero so that all my numbers only display out to the tenths place.

I have tried using the fprintf function as well as the sprintf function but I always lose the rows/column format of my matrix. Is there a way to round and then shorten an entire matrix of numbers so that there aren't any trailing zeros?

 matrix = [1.34, 3.45, 2.34; 0.54, 21.34, 0.34; 11.81, 9.94, 10.02];  %3x3 matrix of data
 round_matrix = round(matrix, 1); %3x3 matrix of data rounded to 1 decimal place 
 %My attempts thus far at removing the trailing zeros
 disp_matrix = sprintf('%.1f', rounded_matrix); %This resulted in a string of all of my numbers mashed together
 disp_matrix = fprintf('%.1f\n',round(Table_outnumeric)); %This resulted in all of my numbers being converted into a single column

How about as follows,

    >> disp_matrix = num2str(round_matrix, '%.1f    '); disp(disp_matrix)
    1.0    0.8
    0.5    0.1

To be clear, though, if you want to a matrix displayed to 1 decimal place, you have no choice but to convert it to string/char type. You cannot force MATLAB to display actual numeric matrix objects to arbitrary customized precision. However, see FORMAT for the display options that you do have.

disp_matrix = sprintf('%.1f ', round_matrix)

This answer results in a single row of numbers:

>> matrix = rand(2,2)
 matrix =

    0.9572    0.8003
    0.4854    0.1419
 >> round_matrix = round(matrix,1)

    1.0000    0.8000
    0.5000    0.1000
>> disp_matrix = sprintf('%.1f ', round_matrix)
disp_matrix =

    '1.0 0.5 0.8 0.1 '

I ultimately want to retain my 2x2 matrix of the rounded numbers like this:

>> round_matrix = [1.0, 0.8; 0.5, 0.1]
   1.0     0.8
   0.5     0.1
