Develop a Excel VBA to solve a system of equations via Gauss elimination (with partial pivoting). VBA should be able to read matrices [A] and {b} of different sizes from the excel spreadsheet, and calculations to solve for solution {x} should be done within the VBA and the solution appear in a message box or on the spreadsheet. VBA may also incorporate LU decomposition. Test the VBA with problem 9.18 and 12.15 from the text.

4. (10 pts) Using the Gauss-Jordan elimination process, solve the following systems of linear equations. How many solutions are there? Can we apply Cramer's rule? Explain why (Use the matrix form of linear equations.) 4. (10 pts) Using the Gauss-Jordan elimination process, solve the following systems of linear equations. How many solutions are there? Can we apply Cramer's rule? Explain why (Use the matrix form of linear equations.)
please help with these 3, thank you!! Use either Gaussian elimination or Gauss-Jordan elimination to solve the given system or show that no solution exists. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, use t for the parameter.)

Problem X. Take the method for finding the inverse of a given n x n matrix A -a by straightforward Gauss (or Jordan) elimination (Problem 7 is a particular case for n 3). First you write down the augmented matrix A and apply the Gauss process to this as discussed in class: A-la2,1 a2,2 a2,n : an,1 an,2 .. an.n 0 0 1 3. Derive the Jordan elimination algorithm without pivoting for the augmented matrix in terms of a triple...
Write a program in Matlab that solves linear systems of equations using Gauss elimination with partial pivoting. Make sure that you use variables that are explicit, and make sure to include comment lines (each subroutine should have at least a sentence stating what it does). Make sure that your program checks for valid inputs in matrix and vectors dimensionality. • Using your code, solve the systems of equations in problems 9.11, 9.12, and 9.13 9.11 9.12 9.13 2x1-6x2-X3 =-38 We...
