The test suite generates a random M x N matrix with a random number of rows and columns that is assigned to the variable A . The element values of the matrix are random double precision numbers that fall in the range from -10 to 10. The matrix has between 5 and 10 rows and between 5 and 10 columns. Assuming A is defined in the workspace, write a script with commands to perform the operations described below and assign the results to the indicated variable names.
- Create a new 2 x N matrix, B, that consists of the first and last rows of A.
- Create a new 2 x 2 matrix, C, that consists of the elements at the four corners of A.
- Create a new M-1 x N-1 matrix, D, that consists of the second through last columns in the second through last rows of A.
