Write a function that solves the matrix equation Ax = b using Gaussian Elimination. Your function should accept as input a n-by-n matrix A and an n-by-1 vector b, and it should produce a n-by-1 vector x that satisfies Ax = b. Gaussian Elimination has two parts: forwards elimination and backwards substitution. You'll need to use both to solve the problem. It's okay to rigidly follow the pseudocode in the book. Using C++ Don't just use a library call, even...

Let A be a square matrix and b be a vector and consider the system Ax = b. Gaussian elimination changes Ax = b to Rx = C, where R is the reduced row-echelon form of A. The solutions to this system are of the form 21 ouw X=1 +11+z1 for any real numbers y and z. 1. Find Randc 2. The row operations taking A to R are the...

(a) In some cases, a matrix may be row reduced to more than one matrix in reduced echelon form, using different sequences of row operations. Is this statement true or false? O A. The statement is true. The echelon form of a matrix is always unique, but the reduced echelon form of a matrix might not be unique. O B. The statement is false. Each matrix is row equivalent to one and only one reduced echelon matrix. O C. The...
