hitfit::Row_Vector Class Reference

Row-vector class. CLHEP doesn't have a row-vector class, so HitFit uses its own. This is only a simple wrapper around Matrix that tries to constrain the shape to a row vector. It will raise an assertion if you try to assign to it something that isn't a row vector. More...

Detailed Description

Row-vector class. CLHEP doesn't have a row-vector class, so HitFit uses its own. This is only a simple wrapper around Matrix that tries to constrain the shape to a row vector. It will raise an assertion if you try to assign to it something that isn't a row vector.

Constructor & Destructor Documentation

hitfit::Row_Vector::Row_Vector ( int  cols )

explicit

Constructor, instantiate an unitialized matrix.

Parameters

cols	The number of columns (the length of the vector).

Definition at line 45 of file matutil.cc.

{
}

hitfit::Row_Vector::Row_Vector ( int  cols, int  init  )

explicit

Constructor, instantiate an unitialized matrix, and initialized it to zero.

Parameters

cols	The number of columns (the length of the vector).
init	A dummy argument, should always be zero.
