Storing data in another array

1 次查看(过去 30 天)
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 20x20 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);
For learning very basic MATLAB operations, such as how to assign a value to a new variable, you should do the (free!) introductory tutorials:

@Wilhelm Concha: MATLAB is not "other programs". Learn to use it, not fight it:
