focus on question 9, 10, 11 please

using matlab

Create the following matrices with the assigned variables. a=[121736]b=512824336c=22174 1. Assign to the variable x1 the value in the second column of matrix a. l.e., 1=aW, 2. Assign to the variable x2 the third column of matrix b 3. Assign to the variable 3 the third row of matrix b 4. Assign to the variable 4 (a vector) the values in matrix b along the diagonal position. 5. Assign to the variable 5 (a matrix) the first three values in the array a as the first row and all the values in matrix b as the second through fourth row. 6. Assign to the variable x6 the values in matrix c as the first column, the values in matrix b as column 2,3 and 4 , and the values in matrix a as the last row. 7 Assign to the variable 7 the value of element 8 in the matrix b, using the single-indexnumber identification scheme. 8. Convert matrix b to a column vector named 8. 9. Type matrix A=356157913541084122111, create a 43 matrix B consisting of all elements in the second through fourth columns of A 10. Create a 34 matrix C consisting of all elements in the second through fourth rows of A. 11. Create a 23 array D consisting of all elements in the first two rows and the last three columns of A
