 ===I have trouble solving Question 5. Could you give us more hints?===

+There are a few ways to write this program. I assume that you have no problem
 reading the input file into a matrix. One way to write the rest of the program is
 to use a loop to go through all the rows in the matrix. In each pass of the loop, you
 take the information in one row of the matrix (which contains a person's height in inches and weight in pounds), call the IPtoCK function to convert these two numbers into cm and kg, calculate the person's BMI based on the converted cm and kg, and then determine this person's BMI category and output a line in the output file (which shows this person's
 height in cm, weight in kg, BMI value and BMI category).
+=== To answer the second question, can we change our answer to the first question so that it can take a vector as the input? ===
-** The first question asks us to write a function that takes a scalar input argument.

-In the second question, we are asked to use this function. However, in the second question
