So I have a for loop that repeats 3 times, the first time my answer needs to have 3 decimal places but then when it runs the second and third time I need to have 4 decimal places. How do I change the number of decimal places between the three loops

Places_to_round_to = [3 4 4];
for K = 1 : whatever
calculate something
YourVariable = round(YourVariable, Places_to_round_to(K));
end

Just index into the vector that you created that specifies the number of places to which you wish to round for that iteration in the loop.
YourVariable = round(YourVariable, Places_to_round_to(K));
