Detailed Description

Non-owning view into a rectangular sub-region of a matrix.

Wraps a gsl_matrix_view. The referenced data is owned by the original matrix — the view must not outlive it. Assigning to a view modifies the underlying data in place. Use operator matrix() to obtain an independent copy.

private

matrix_view() [2/2]

dvrlib::matrix_view::matrix_view

(

const matrix_view &

)

Copy constructor (shallow — both views reference the same data).

Member Function Documentation

get()

double dvrlib::matrix_view::get	(	int	i,
		int	j
	)		const

Return element (i, j).

gsl_internal()

const gsl_matrix * dvrlib::matrix_view::gsl_internal

(

)

const

Return a read-only pointer to the underlying gsl_matrix.

operator matrix()

dvrlib::matrix_view::operator matrix

(

)

const

Create an independent matrix copy of this view.

operator=() [1/2]

matrix_view & dvrlib::matrix_view::operator=

(

const matrix &

src

set()

void dvrlib::matrix_view::set	(	int	i,
