Write a program implementing Gaussian elimination. Run your program with the given input les. Turn in: - This problem sheet with your name. - A summary sheet explaining what you did, how you approached the problem, what was accomplished, what was not accomplished, etc. Website: - Create a directory called 3gauss on your web site and make all your input, output and source les available in this directory. Write the url for the website on this problem sheet. Input: The augmented matrix of an n n linear system of equations. Each line represents a row of the matrix. The entries of the matrix are separated by spaces. Output: The values of the variables n in a row, separated by a space. The output should be the sentence No unique solution if the system has no solutions or innitely many solutions. Sample input: 321 532 Sample output: 1 -1 Hints: - Write separate functions for reading in the data, elimination and back substitution. Start with the given skeleton program. - Use operator overloading to calculate the the scalar multiple of a vector and the sum of two vectors. Take a look at matrixexample.C. This will greatly simplify your code. - You can sw...
