1. Read the matrix from the file. Let us call this matrix (X).
2. Compute the sum of the third column of X.
3. Dot product of the first and the last rows of X.
4. Use the last six values of the fourth row of X in order to create and display a 6x6 diagonal matrix, call it (Z).
5. Compute the inverse matrix of Z.
6. Partition X into two 20x10 matrices, say A and B, where A has only odd numbered rows and B has only even numbered rows. That is, A contains 1st, 3rd, 5th, …. rows of X, while B contains 2nd, 4th, 6th,… rows of X.
7. Compute the sum of all the elements of A.
8. Compute the sum of all the elements of B.
9. Create 20x10 matrix, say C, where(i,j) elements is
-1 = if A(i,j) < B(i,j)
0 = if A(i,j) = B(i,j)
1 = Otherwise
10. Find the median of the 10th row of X.
