Modify the function developed for problem 23 so that the row pivoting is performed before each variable is eliminated. Use the function developed in problem 24.
Use the program developed in Section 8.4 as a guide to develop a function that receives a double array a of size by . A second parameter is a double array soln of size . The function should solve the system of equations represented by array a, and return the solution in array soln. Assume that the corresponding function prototype is
Write a function that receives a two-dimensional array and a pivot value that specifies the coefficient of interest j. The function should then reorder all equations starting with the jth equation such that the jth equation will have the largest coefficient (in absolute value) in the jth position. Assume that the function can reference the size of the array as by , and that the corresponding function prototype is
