The average of the numbers in the vector “v” is calculated by summing all the individual values, and then dividing the sum by the number of numbers in “v”.

  1. A) Create program code for function file “average” which takes as the input vector “v” and uses a for-loop to calculate the average of all the numbers in “v”. Hint: To determine the number of numbers (n) in the vector “v” you can use n = length (v) . Your code must begin with

function x = average (v)

b) Let T be a table with n = 100 rows and m = 100 columns. Write a program that, using pre-loop and if-testing, counts the number of columns in T that have an average value of less than 10.

HINT: You retrieve a copy of column number k in table T by typing t = T (:, k);
