For Matlab

write a function A-myMatrix (n), which create sann-by-n matrix A with elements Aj-1/(i-/)ifi# j and 1 otherwise. Test your function for the case n-5 Consider the sequence (a,ay,a) defined recursively by an -an- for a given positive number ao- Write a Matlab function which computes the sum ao + al + a2 + + aN. Your function should have ao and N as inputs. and the resulting sum as the output. Test your function with ao = myvec ( 1 ) and N = length (myvec)
