Please solve the following problem in Matlab

Homework Problem 2: Fun with Arrays Part A: Write a script file called padrv.m. At the start of this file, you will create a row vector v, and define an integer n, where n is greater than the length of the vector v. Your code will insert zeros at the beginning of v so that the length becomes n. For example, if v and n are defined as follows: v= [1-4 2?4] and n = 8, then your code should calculate the new v to be [o o o 1-4 2 0 41. Part B: Write a script file called unpad.m, which creates a row vector, removes all zeros at the beginning of the vector, and returns the remaining elements of the vector (i.e., it drops the zeros at the beginning of the vector). Assume that at least one element in the array w is non-zero. For example, w= [0 0 0 1-4 2 0 4], then your code should calculate the new w to be [1-4 2 0 4]. An important case to check your code is that if your vector does not start with zeros, it should return the same vector. If w [1 -4 2 o 4], then your code should calculate the new w to be [1 -4 2 0 4]. For this problem you will turn in two files padrv.m and unpad.m
