Create the following matrix M (do not type individual elements explicitly): 3 9 27 81 16 12 8 4 5 15 25 35 100 83 66 49 Do not type individual elements explicitly, use the matrix M to: (a) Delete the fourth row of matrix M and put the new matrix in MN, then create a 3x3 matrix named A that contains the first, second and fourth columns of MN. (b) Add a fifth row to the matrix M with the elements similar to that of the third column, then find the matrix summation and average and display the results using the fprintf command. solve in matlab | im dybala (c) Create a seven-element column vector named B that contains elements 1, 2, 4,5 of the second column of M, followed by elements 4, 2, 1 of the third row of M.

Create the following matrix M: M = 1 13 19 25 3 15 21 27 5 11 17 23 29 By writing one command and using the colon to address range of elements (do not type individual elements explicitly), use the matrix M to: (a) Create a five-element row vector named Va that contains the elements of the third row of M. (b) Create a three-element column vector named Vb that contains the ele- ments of the fourth column of M. (c) Create an eight-element row vector named Vc that contains the ele- ments of the second row of M followed by the elements of the third col- umn of M.

Give the code asked in the question using the GNU Octave App. Do not type individual elements explicitly.

3. Load the file thermocouple.dat. Save the data in a matrix named thermo- couple. (a) Create a column vector named times going from 0 to 24 in 2-hour incre- ments. (b) Combine the times vector you created in part (a) with the data from thermocouple to create a matrix containing the times and the thermo- couple data. (c) Recall that the max and min functions can return not only the maximum and minimum values in a column, but also the element number where those values occur. Use this capability to determine the values of times at which the maxima and minima occur in each column. PARTNERE ME
