Chapter 15.6, Problem 20CC

Assume a cell array named CA has three cells in a single row

• The first cell contains a name in the formal X. Y. Family.

• For example: M. V. Smith

• The second cell contains a 2×3 matrix. For example: [1 3 5; 9 6 3]

• The third cell contains a 3×2 matrix. For example: [4 7; –2 –6: 0 1]

1. a. Extract the family name (Smith in the example above) from 1he first cell and place it in column one of a newly created second row of CA. Your solution should work for family names of any length. Note that the first six characters of the name in the first cell will always be the two initials, each followed by a dot and a space.
2. b. Multiply the matrix in the second cell of row 1 by the matrix in the third cell of row 1 and place the result in the second row, second column of CA.
3. c. Calculate the element-wise product of the matrix in row 1, column 2 with the transpose of the matrix in row 1, column 3. Place the result in the third column of the second row of CA.
