if v1 is [1 2 3 4 5 6 7 8] then v2 should be [3 5 7 9 11 13 15].
if v1 is [1;
then v2 should be [4;

Getting the indices from a vector
Find the average of a random sequance
Rearrange the given matrix to have all its zeros climb up to the top of each column - using for loops.
Given a matrix A return a vector of the product of the elements in each column using a loop without using prod.
Given a matrix A (size m x n) create a matrix B (size m+2 x n+2) which consists of matrix A surrounded by zeros. See Example below:
Given a matrix A (size m x n) create a matrix B which consists of matrix A sorted in descending order by columns and then by rows.
