4. Write a Matlab function called HW1P4 that is passed 2 column vectors. The function will take the square root of each element of the first vector, subtract one half of the corresponding element of the second vector, and return the resulting vector. Put the function in a separate file. Show the code for the function and from the Matlab command window call the function with the first vector equal to [7; -3; 16) and a second vector equal to [29; -44; 32] and show the result
