Write a Matlab statements that will accomplish the following tasks: a. Extract the fourth row and save it in variable named a. b. Summation of each raw in matrix M and save it in variable named b. c. Extract the following sub-matrix and save it in a variable named c. d. Insert the following vector v= [4, 4, 4, 4] between column three and four and save the new matrix in a variable named d. e. Find the actual position (indices) of the negative elements and save them into variables. f. Convert the matrix M into one column vector and save it in a new variable named g. Summation of the diagonal elements in M and save it in a variable named g. h. Multiply the matrix M by a number 7 and save new matrix in a variable named h. i. Replace the last column elements in M by 10 and save new matrix in a variable named I. Write a Matlab statements that will accomplish the following tasks: a.
