Write a multi-thread program to handle two matrices, A and B. Randomly generate the content of matrix A and B withi specified dimension provided as two command arguments. Dimension of A and B must be the same. Then create three threads: a. one thread will transpose the A and B b. one thread will calculate addition of two matrices as C= A + B c. one thread will calculate subtraction of two matrices as C-A-B Also print out the results for each thread. Remember to allocate space for C and the transposed A and B. The following image shows a transposed matrix. A = e #include #include 2x3 #include #include Sample Array Statistics Solution that we discussed in class: //From OS concepts of John Wiley & Sons //please run this program as ./main 3567246 // It is up to you as what integer array to supply as the arguments. /* the list of integers */ int "list; int maximum; int minimum; AT= b /* the threads will set these values */ double average: a d void *calculate_average(void *param); void "calculate maximum(void *param); 3x2
