uppLim = length(value) - 1;
Should solve your problem. Oh and drop the
while value
which is basically an endless loop because value doesn't change inside the loop. it's also not necessary because the
for i = 1:uppLim
doesn't enter the loop when value is empty.
I would also ditch the for loop, and vectorize it
list = input('Enter a list of positive intergers separated by commas:', 's');
value = strsplit(list, ','); value = str2double(value);
x = sum(value([false diff(value) > 0]));
disp(['The sum of the numbers = : ' num2str(x)]);
