C = input('Enter a vector of coefficients for an odd-order polynomial: ');
valC = length(C);
count = 1;
while mod(valC,2) == 1
C = input('Try Again. Enter a vector of coefficients for an odd-order polynomial: ');
count = count + 1;
if count > 4
warning('Odd number of coefficients entered. Last element of user input removed.');
C(:,end) = [];
end
end
When the count variable reaches 5 I just want to produce the warning and remove the last number from the C array but when I run it, MATLAB produces the warning and removes the variable however it just starts the loop over again instead of ending after the last number in C array is removed.

C(end) = [];
break;
end
end
Question: what do you want to do if the user enters the empty array -- such as if they just press return.
