1.How to replace the second column of A with the vector v = [1,-2,4]' for the following matrix

A=(1 2 3 4 5 11 12 13 14 15 21 22 23 24 25) without using spaces or semi colons.

2.For the same matrix above mentioned, each row of A, we want to calculate the square of the norm using the function sum and elementwise operations.
