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(int, char *[])
{
  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;
}

Classes demonstrated

template<typename T, unsigned int NRows = 3, unsigned int NColumns = 3>
class Matrix

A templated class holding a M x N size Matrix.

This class contains a vnl_matrix_fixed in order to make all the vnl mathematical methods available.
