Q5 MATLAB

Exercise 35 (a) Try using the inv command to find the inverse of the matrix 100 100 Notice the strange output. Include your command and the output in the final write up. (b) Now enter the following matrix A into MATLAEB A [4, 9: 5, 11 Let us find its inverse: B inv(A) and check that it satisfies the definition. Enter the following commands >AB >B*A Include your commands and the output they produced in the final write up (MATLAB may give you entries such as -0.000 as the result of multiplying the matrices above. Don't pay too much attention to that. -0.000 is still 0 for all practical purposes.) (c) Enter the following column vector into MATLAB: [5i10 Now multiply A by x by entering the following command: As usual, include your input and output in the final write up d) Now without entering anything into MATLAB (no cheating!), what do you think will be the result of B*y? Explain your answer. (e) Check your answer to the above question, by entering the appropriate commands into MATLAB. Include the input and output in your Word document
