Create MATLAB variables to represent the following matrices, and use them in the exercises that follow: a=[12 17 36] b=[5 8 3;1 2 3;2 4 6] c=[22;17;4] 1. Assign to the variable x1 the value in the second column of matrix a . 2. Assign to the variable x2 the third column of matrix b . 3. Assign to the variable x3 the third row of matrix b . 4. Assign to the variable x4 the values in matrix b along the diagonal (i.e., elements b 1,1 , b 2,2 , and b 3,3 ). 5. Assign to the variable x5 the first three values in matrix a as the first row and all the values in matrix b as the second through the fourth row. 6. Assign to the variable x6 the values in matrix c as the first column, the values in matrix b as columns 2, 3, and 4, and the values in matrix a as the last row. 7. Assign to the variable x7 the value of element 8 in matrix b , using the single-index-number identifi cation scheme. 8. Convert matrix b to a column vector named x8 .
