/* * @name {\bf DMatrix/DMatrixSlice Assignment Fucntions}.
  *
  * These are functions for assigning one matrix to another.  The rhs matrices
  * can be transposed (op(rhs) = rhs) or non-transposed (op(rhs) = trans(rhs).
  * The assignment operators for
  * DMatrix and DMatrixSlice use these functions to implement their
  * assignment operator functions.  The assignmet functions for triangular
  * matrices are ment to be called from the assignment operator functions
  * for wrapper classes for triangular (upper and lower) and sysmetric 
  * (upper and lower storage).
  *
  * These assignment functions check for aliasing and assignment to self
  * and create any needed temporaries if needed.
