L  Construct and store a 4 x 2 matrix that is filled row-wise with the values 4.3, 3.1, 8.2, 8.2, 3.2, 0.9, 1.6, and 6.5, in that order. 2. Check the dimensions of the matrix. 3. Remove the second row from the matrix in 1. 4. Confirm that the dimensions of the matrix from (1) are 3 x 2 if you remove any one row. 5. Overwrite the second column of the matrix from (1) with that same column sorted from smallest to largest. 6. Store the bottom four elements of (3) as a new 2 x 2 m
