XprMatrix< MatrixConstReference< T, Rows, Cols >, Rows, Cols > cmatrix_ref ( const T *  mem )

Creates an expression wrapper for a C like matrices.

This is like creating a matrix of external data, as described at construct. With this function you wrap an expression around a C style matrix and you can operate directly with it as usual.

Example:
 static float lhs[3][3] = {
   {-1,  0,  1}, { 1,  0,  1}, {-1,  0, -1}
 };
 static float rhs[3][3] = {
   { 0,  1,  1}, { 0,  1, -1}, { 0, -1,  1}
 };
 ...

 typedef Matrix<float, 3, 3>            matrix_type;

 matrix_type M( cmatrix_ref<float, 3, 3>(&lhs[0][0])
                *  cmatrix_ref<float, 3, 3>(&rhs[0][0]) );

Fill a matrix to an identity matrix.

Fill a matrix to an identity matrix (convenience wrapper for matrix typedefs).

Note:
The matrix doesn't need to be square. Only the elements where the current number of rows are equal to columns will be set to 1, else to 0.
Usage:
 typedef Matrix<double,3,3>        matrix_type;

 matrix_type E( identity<double, 3, 3>() );

Note, we have to specify the type, number of rows and columns since ADL can't work here.

tvmet::TVMET_IMPLEMENT_MACRO ( int   )

eval(const XprVector<E, Sz>& e, std::complex<T> z2, std::complex<T> z3)

Evals the vector expressions.

This eval is for the a?b:c syntax, since it's not allowed to overload these operators.
