Enter the matrices:
1 0 9 2 3 7 A=1 20 | 4 15 B=21 4 3 1 2
a. Define the row vector a as the first row of matrix A, by selecting the elements from A.
b. Define the column vector b as the first column of matrix B, by selecting the elements from B.
c. Define scalar c as the element in row 2, column 3 of matrix B, by selecting the element from B.
d. Define the submatrix C as the 2 x 2 upper-left submatrix of A, by selecting the elements from A.
e. Construct a row vector x, consisting of: 1, 1.08, 1.16, ..., 1.88
f. Construct a column vector y that is the transpose of vector x.
g. Concatenate matrices A and B, with B underneath A.
2. Enter the vectors: X= 2 y = 3 4
a. concatenate x and y so that y is to the left of x;
b. concatenate x and y so that y is underneath x.
3. Create a new matrix, A_new, containing only the 1st and 2nd rows of the given matrix A (from problem 1), by deleting row 3 of A.
