Write Matlab Code.

The sum of integers between 1 and n is given by sigma_j=1^n i = n(n+1)/2. Write a Matlab script that prompts the user for an integer n and reports the sum three ways a. using the algebraic formula above. b. using a counting (for) loop c. using a while loop (The three parts can be done in one script. The filename should be hw06_01. m.)
