template<class elem_t >

size_t LocARNA::OMatrix< elem_t >::addr	(	size_t	i,
		size_t	j
	)		const [inline, protected]

Computes address/index in 1D vector from 2D matrix indices.

Shifts indices by offset

Parameters:

i	first index
j	second index

Returns:

index in vector

Note:

this method is used for all internal access to the vector mat_

template<class elem_t >

const elem_t LocARNA::OMatrix< elem_t >::get	(	size_t	i,
		size_t	j
	)		const [inline]

Read access to matrix element

Parameters:

i
j

Returns:

entry (i,j)

Note:

: redefine since we don't want to use polymorphism

template<class elem_t >

const elem_t& LocARNA::OMatrix< elem_t >::operator()	(	size_t	i,
		size_t	j
	)		const [inline]

Read access to matrix element

Parameters:

i
j

Returns:

entry (i,j)

Note:

: redefine since we don't want to use polymorphism

template<class elem_t >

elem_t& LocARNA::OMatrix< elem_t >::operator()	(	size_t	i,
		size_t	j
	)		[inline]

Read/write access to matrix element

Parameters:

i
j

Returns:

reference to entry (i,j)

Note:

: redefine since we don't want to use polymorphism

template<class elem_t >

void LocARNA::OMatrix< elem_t >::resize	(	size_t	xdim,
		size_t	ydim,

		size_t	yoff = 0
	)		[inline]

Resize matrix

Parameters:

xdim	new first dimension
ydim	new second dimension
xoff	new offset in first dimension
yoff	new offset in second dimension

template<class elem_t >

void LocARNA::OMatrix< elem_t >::set	(	size_t	i,
