I would like to write the summation

Something like this

p = 10;
q = 12;
up_lim = min(p, q);
f = @(x) sum((x-1).^(0:up_lim));

Result

>> f(0)
ans =
     1
>> f(0.5)
ans =
    0.6670
>> f(1)
ans =
     1
>> f(2)
ans =
    11
>> f(5)
ans =
     1398101

min() cannot be used for symbolic variables. You cannot use it in this code.

@Ameer: Thanks. yes. It can't be used as min(). I was wrong.
