write a sub-routine that performs forward and backward substitution in a column-oriented manner in fortran 90. To test your code compute b = Ax where x = (1,1,.....,1)expT. Then use your code to solve b = Ax' + compare x with x'. For A use the upper and lower portions of the hilbert matrix. Turn in a copy of your code + the results for n = 10.
