Chapter 15.4, Problem 17CC

For each of the following questions, write a single MATLAB command that will achive the stated goal.

1. a. Create a Matrix HSR defined as the square root of half of each element in matrix QPD.
2. b. Replace the second row of matrix OPD with the cube of each of those elements divided by the natural logarithms of the corresponding elements in row 3 of OPD,
3. c. Assume matrix M3R contains exactly three rows. Modify M3R so that the top and bottom rows are swapped.
4. d. Assume MOC=[1 0 4 –5 –2; 9 –4 0 –7 0; 3 9 55 –1 0];

    What is placed in MCCR and MCCC by' the command

   [MCCR,MCCC]-find(MCCR—1);
