Detailed Description

template<class T, unsigned M = 0, unsigned N = 0>
class mth::Matrix< T, M, N >

compile-time (static) matrix

Definition at line 23 of file mthMatrix.h.

Constructor & Destructor Documentation

Matrix()

template<class T , unsigned M = 0, unsigned N = 0>

mth::Matrix< T, M, N >::Matrix ( unsigned  m, unsigned  n  )

inline

construct with m by n elements

A dummy constructor Matrix(m,n) is provided so that dynamic and static matrices can be used interchangebly

Definition at line 31 of file mthMatrix.h.

{ (void) m; (void) n; }

Member Function Documentation

operator()() [1/2]

template<class T , unsigned M = 0, unsigned N = 0>

T& mth::Matrix< T, M, N >::operator() ( unsigned  i, unsigned  j  )

inline

mutable index operator

An index operator (i,j) is provided so that compile time matrices and runtime-sized matrices can be used interchangebly, without worrying about changing index syntax

Definition at line 40 of file mthMatrix.h.

{return (*this)[i][j];}

operator()() [2/2]

template<class T , unsigned M = 0, unsigned N = 0>

T const& mth::Matrix< T, M, N >::operator() ( unsigned  i, unsigned  j  ) const

inline

immutable index operator

see the mutable index operator details

Definition at line 43 of file mthMatrix.h.

{return (*this)[i][j];}

operator*()

template<class T , unsigned M = 0, unsigned N = 0>

template<unsigned O>

Matrix<T,M,O> mth::Matrix< T, M, N >::operator* ( Matrix< T, N, O > const &  b ) const

inline

multiply two matrices

the extra template parameter generates code for all possible combinations of matrix sizes

Definition at line 88 of file mthMatrix.h.

    {
      Matrix<T,M,O> r;
      for (unsigned i=0; i < M; ++i)
      for (unsigned j=0; j < O; ++j)
      {
        r[i][j] = this->elems[i][0]*b[0][j];
        for (unsigned k=1; k < N; ++k)
          r[i][j] += this->elems[i][k]*b[k][j];
      }
      return r;
    }
