Jacobi Method Implementation in Fortran

Classified in Computers

Written on in English with a size of 3.12 KB

This section details the implementation of the Jacobi method in Fortran for solving a system of linear equations. The subroutine solucion_Jacobi takes a matrix A, a vector b, and an initial guess X as input, and returns the solution vector X.

Subroutine: solucion_Jacobi(A, b, X)

The subroutine begins with the following declarations and initializations:

  • use normas
  • integer, parameter :: Kx = 100
  • real(8), parameter :: tolerancia = 1E-6
  • real(8), allocatable :: X0(:), ERROR(:)
  • real(8), intent(in) :: A(:,:), b(:)
  • real(8), allocatable, intent(out) :: X(:)
  • integer :: i, j, k, n
  • real(8) :: sum, zero, ek

Where:

  • Kx is the maximum number of iterations.
  • tolerancia is the error tolerance.
  • X0 is the previous iteration's solution vector.
  • ERROR is the error vector.
  • A is the

The Id

  • The Id represents the primal drives and impulses of the child.
  • It is the only part of the personality that functions at birth.

The Ego

  • The Ego develops during infancy and mediates between the Id and the external world.
  • It seeks to satisfy the Id's impulses in a socially acceptable manner.

The Superego

  • The Superego emerges around the age of 4-5 years.

THOREAU’S CIVIL DISOBEDIENCE

Perhaps the most famous text in the literature of romantic reform is Henry David Thoreau’s essay, Resistance to Civil Government (1849), better known as Civil Disobedience. The occasion of the essay was Thoreau’s refusal to pay a poll tax in the town of Concord in protest of the United States war with Mexico (1846– 1848). Thoreau regarded the war as a conspiracy to seize Mexican lands and enable the expansion of southern slavery. Thoreau was jailed for his refusal to pay the tax. His essay is a defense of his actions as well as a treatise on the moral and political responsibilities of the citizen. In Civil Disobedience, Thoreau argues that, in an ideal world, governments would be rendered unnecessary;
