Try using the inv command to find the inverse of the matrix Notice the strange output. Include your command and the output in yo

ur write-up. Now enter the following matrix A into MATLAB: >> A = [4 9; 5 11] Define B to be its inverse in MATLAB. Then run the commands >> A*B >> B*A to check that it satisfies the definition of inverse. Include your commands and their output in your write-up. (Note that MATLAB may give you entries like -0.0000 in your results. This still counts as 0 for our purposes.) Enter the following column vector x: >> x = [5; 10] Use the following command to multiply A by x: >> y = A*x As usual, include your input and output in your write-up. Without entering anything into MATLAB, what do you think you'll get if you multiply B by y? Explain your answer.
