How can I accomplish the following?

Question

0 个投票

Use for loop to display the following numbers in sequence separated by “,”

1, 2, 3, 4, 5, 6, 7, 8, 9, 10

this is what I have so far but I can't figure out how to get rid of the coma after the 10.

A1=' ';
for i=1:1:10
  A2=[num2str(i),','];
  A1=[A1,A2]; 
end
disp(A1)

A1=' ';
for i=1:1:10
if i<10
A2=[num2str(i),','];
else
A2=num2str(i);
end
A1=[A1,A2]; 
end
disp(A1)

You can probably do it more efficiently than this, though..

Thankyou been banging my head on this for the last four days.

Try this:

m = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
str = sprintf('%d, ', m);
fprintf('\n%s\n', str(1:end-2));

This is a question from an introductory Matlab course at my local college and I need to use a for loop to produce this.

A1=' ';
for i=1:1:10
  if i <= 9
    A2=[num2str(i),','];
  else
    A2 = num2str(i);
  end
  A1=[A1,A2]; 
end
disp(A1)
