operator RWGenMat<To>()

RWConvertGenMat<From,To>()

template <class From, class To>
class RWConvertGenMat;

Class RWConvertGenMat<From,To> converts between RWGenMats with different datatypes. It assumes that there is a conversion operator from From to To.

#include <rw/math/genmat.h>

int main()
{
       // create a 2x2 matrix
   RWGenMat<int> d("2x2[1 2 3 4]");

       // convert int matrix d to DComplex 
       // matrix c with imag part 0
   RWGenMat<DComplex> c = RWConvertGenMat<int,DComplex>(d); 

       // convert int matrix d to a double 
       // matrix and then call sin
   function RWGenMat<double> s = RWConvertGenMat<int,double>(d);
            s = sin(s);
}

RWConvertGenMat<From,To>(const RWGenMat<From>& M);

Constructs a new matrix of type RWGenMat<To> that can be used anywhere as a type RWGenMat<To>. Note that a temporary matrix is created every time this constructor is invoked, but the conversion operator below can be used repeatedly without creating additional temporary matrices.

operator RWGenMat<To>();

Automatic conversion operator that enables class RWConvertGenMat<From,To> to be used as an RWGenMat<To>. While the actual conversion takes place in the constructor, this operator provides a reference to that converted matrix.
