In how many ways can you create this matrix using submatrices A, B, and C (that is, you are not allowed to enter the nonzero numbers explicitly)? 2600 00 3900 00 0012 00 G= 0034 00 0000-55 0000 5 3 5. Manipulate a matrix: Do the following operations on matrix G created in Exercise 4. . Delete the last row and last column of the matrix. Extract the first 4 x 4 submatrix from G. Replace G(5,5) with 4. What do you get if you type G(13) and hit return? Can you explain how MATLAB got that answer? What happens if you type G(12,1)=1 and hit return?
