Write a program that receives an integer (n) and then calculate the sum of integers 1 to n (exp. 1 + 2 + 3 + ….. + n) using for loop
so confused :(

As a last desperate measure you could simply write:
the_sum = n*(n+1)/2;
as Gauss is said to have correctly done in his primary school years.

Use inputdlg() to get n - look in the help for examples. Then use a for loop. Here's a hint to get you started.
theSum = 0;
for k = 1 : n
% your code goes here.
theSum = theSum + ........
end
I don't know what you mean by exp. Do you want e to the power? Like exp(1) + exp(2) + exp(3) + .... OR do you want exp(1+2+3+.....????
