I just need help with 2a-c please. Problem 1 is sjown for context for c. In MATLAB please

context for c. In MATLAB please 1 SOLVE A SYSTEM WITH LU

1 SOLVE A SYSTEM WITH LU DECOMPOSITION (a) Define matrix A and vector bas (1.1). 7 -26 45-47] 1 2 3 4 2-11 -12-13 4-17 30 35 11 2 13 24 1-98 30 -108 200 (1.1) (b) Calculate the LU decomposition L, U of the matrix A. (c) Solve the following system (1.2) and store the solution to z. Lz = b. (1.2) (a) Then solve the following system (1.3) and store the solution to x. Ux=z. (1.3) (e) Check your solution by calculating the norm of the residual ||Ax - bl2 and store the result to res
