At first I would omit the repeated tests like:
if dot9(1)>=0 && dot9(1)<=16 && dot9(1)>=0 ...
If "dot9(1)" is greater equal zero in the first test, this is true for the 2nd test also.

Numbering the names of the variables is simply a bad programming technique. See Answers: FAQ How to create A1,A2,... in a loop.

as you said i have to get the function by for from the first...
but this code is not working dear Jan:
%
num=input('Enter The Function quantity:')
for i=1:num
function(i)=input('Enter The i function');
end
I Want This But I couldn't reach this
