The following method is used to solve Simultaneous Equation EXCEPT

• Newton Raphson

• Doolittle

• Crout

• Gaussian Elimination

Answer explanation

Newton Raphson method is used to solve non linear equation

Which one of the following methods is NOT LU Decomposition Method

• Crout

• Gaussian Elimination

• Doolittle

• Cholesky

Answer explanation

LU decomposition of a matrix is the factorization of a given square matrix into two triangular matrices, one upper triangular matrix and one lower triangular matrix

The following steps is TRUE for Doolittle Method...EXCEPT

• A=LU

• Ly=b

• Ux=y

• A=Ux

Answer explanation

DON'T WORRY..... BE HAPPY

Choose the CORRECT steps in DOOLITTLE METHOD

• Ax=b

  A=LU

  Ux=y

  LY=b

• Ax=b

  A=LU

  LY=b

  Ux=y

• Ax=b

  Ux=y

  A=LU

  LY=b

• A=LU

  Ax=b

  Ux=y

  LY=b
