MATLAB: Storing data in another array

storing in seperate arrays

Hello
I'm trying to store data in a separate array and was wondering how to do so, an example of my cod will be down below. My data is a 20×20 array of numerical values. What i've achieved is rounding the data in my array to 2 decimal places, but i dont know how to store the newly rounded data in a separate array. How do i create another array the same size and store the newly rounded data in there?
mydata = dlmread('data-1.csv',',');
MAX_ROWS = size(mydata,2);
MAX_COLUMNS = size(mydata,1); 
% Rounding data to two decimal places
for r = 1:MAX_ROWS
    for c = 1:MAX_COLUMNS 
        mydata(r,c); 
          round(mydata,2);
          errorMap(r,c);
      end
  end

Why do you need all of those loops? There is no point in making your code much more complicated than it needs to be:
 mydata = dlmread('data-1.csv',',');
 newData = round(mydata,2);
