Well, my problem is that within the for loop im printing the number of iterartions and the old means using fprintf. The only problem is that it adds a extra comma to the end of the old means when its not needed. I have treid to google the solution, still can't find an answer. Below is the code when i print the iterations and the old means.
I have also attached a picture of what it looks like.
for i =1:I
fprintf("\n Iterations: %d \n",i );
fprintf(" Old Means: ");
