1- - For linear equations of find the solution for x and y, using: a. Row picture (geometrical method; manually) b. Column picture (geometrical method; manually) C. Matrix form (numerical method; manually) 2- Solve the previous problem for 038 Either of manual computation or software programing are acceptable in this problem. 3- Write a MATLAB program that receives matrix A and regardless of its dimension, would return its inverse as output, by using elimination method. 4- Use elimination method to find the inverse matrix of 1 2 1 4 3 4 3 A=54321 42224 01201 After manual calculation, use your MATLAB code in previous problem to check your answer. 5- A linear system with matrix equation of AX=b = (in R3) could be considered as three planes with/without intersections. Find all configurations (of planes) which do not result in a unique solution for this equation. 6- Compute L (total elimination matrix) and U (upper-triangular matrix resulted from eliminating A) for the symmetric matrix A: aaaa abbb A = abcc =LU abcd find four conditions on a, b, c, d SO that the elimination could be applied on A. After manual calculation, use MATLAB in order to verify your results.
