(20 points) Create a 4x5 matrix T in which the first row contains the numbers -2 thru 2, the second row shows the corresponding absolute value, the third row shows the corresponding square, and the fourth row shows the corresponding cube. First, display T and then display the text description for each number, such as for the number -2 showing: If the number is: -2, its absolute is: 2, its square is: 4, its cube is: 8 Save this into a script named "hw0203.m". Give the MATLAB script file and the resulting display.
