Matrix Inverse#

Synopsis#

This will compute and display an NxN matrix and its inverse.

Results#

Output:

M: 1 2
   3 5
Inverse: -5 2
          3 -1

Code#

C++#

#include <itkMatrix.h>

#include <iostream>

int
main()
{
  using MatrixType = itk::Matrix<double, 2, 2>;
  MatrixType M;
  M(0, 0) = 1.0;
  M(0, 1) = 2.0;
  M(1, 0) = 3.0;
  M(1, 1) = 5.0;

  std::cout << "M: " << M << std::endl;

  MatrixType Minv(M.GetInverse());

  std::cout << "Inverse: " << Minv << std::endl;

  return EXIT_SUCCESS;
