By writing one command and using the colon to address ranges of elements (do not type individual elements explicitly), use the matrix a to: create a six-element row vector named p1a that contains the elements of the second row of a. create a 3 x 2 matrix named p1b whose first column is the sixth column of a and the second column is the first 3 elements of row 2 in a. create a five-element row vector named _p1c_that contains the first two elements of the third row of a and the last three element of the first row of a.

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)
