Printing the entire array row in Matlab

I want to print all the rows on the same line of array a and b. How would i be able to do that?

a = [12,3,4,5];
b= [4,5,12,3];
fprintf('a: %d\nb: %d',a, b)

Output:

a: 12
b: 3a: 4
b: 5a: 4
b: 5a: 12
b: 3

Expected output

a: [12,3,4,5]
b: [4,5,12,3]

a = [12,3,4,5];
b= [4,5,12,3];
fprintf(['a: ' repmat(' %1.0f ',1,numel(a)) '\n'],a);
fprintf(['b: ' repmat(' %1.0f ',1,numel(b)) '\n'],b);

..

a:  12  3  4  5 
b:  4  5  12  3

@KALYAN ACHARJYA, looks fine but add the enclosing brackets that he wanted and post the code down in the Answers section.

a = [12,3,4,5];
b = [4,5,12,3];
fprintf('a: [%s]\n', join(string(a), ','));

a: [12,3,4,5]

fprintf('b: [%s]\n', join(string(b), ','));

b: [4,5,12,3]

+1 vote for teaching everyone about join() and string(). 👍

a = [12,3,4,5];
b= [4,5,12,3];
fprintf('a: [')
fprintf('%d, ', a(1:end-1))
fprintf('%d]\n', a(end))
fprintf('b: [')
fprintf('%d, ', b(1:end-1))
fprintf('%d]\n', b(end))
