Function Documentation

◆ gridpos_poly() [1/2]

void gridpos_poly	(	ArrayOfGridPosPoly &	gp,
		ConstVectorView	old_grid,
		ConstVectorView	new_grid,
		const Index	order,
		const Numeric &	extpolfac
	)

The maximum difference from 1 that we allow for a sum check.

The sum check makes sure that the sum of all weights is approximately 1.

We cannot use a sharp comparison there, due to numerical noise. The value of 1e-6 is an ad-hoc value.

This shold be ok, the main point of the test is to make sure that what we have really are interpolation weights, and not something else. Set up grid positions for higher order interpolation.

This function performs the same task as gridpos, but for arbitrary orders of interpolation. (Linear is also possible, as a special case.) We even handle nearest neighbour interpolation, as order 0.

The formula for calculating the weights w is taken from Numerical Recipes, 2nd edition, section 3.1, eq. 3.1.1.

Parameters

gp	Output: An array of grid positions.
old_grid	Original grid.
new_grid	New grid.
order	Interpolation order. 0 = nearest neighbour, 1 = linear, 2 = quadratic, etc.. The number of points used in the interpolation will be order+1.
extpolfac	Extrapolation fraction. Should normally not be specified, then the default of 0.5 is used.

void gridpos_poly	(	GridPosPoly &	gp,
		ConstVectorView	old_grid,
		const Numeric &	new_grid,
		const Index	order,
		const Numeric &	extpolfac
	)

gridpos_poly

Creates a grid position structure for higher order interpolation.

This is a gateway to the function for arrays of GridPosPoly, to be used for e.g. "red interpolation".

Return values

gp	The GridPos structure.

Parameters

old_grid	The original grid.
new_grid	The position where we want to have the interpolated value.
order	Interpolation order. 1 = linear, 2 = quadratic, etc.. The number of points used in the interpolation will be order+1.
extpolfac	Extrapolation factor. Default value is 0.5, which means that extrapolation of half of the last grid distance is allowed. You don't have to specify this.

◆ gridpos_poly_cyclic_longitudinal() [1/2]

void gridpos_poly_cyclic_longitudinal	(	ArrayOfGridPosPoly &	gp,
		ConstVectorView	old_grid,
		ConstVectorView	new_grid,
		const Index	order,
		const Numeric &	extpolfac
	)

Set up grid positions for higher order interpolation.

This function performs the same task as gridpos, but for arbitrary orders of interpolation. It is especially for cyclic interpolation of longitudes. The distance between the first and the last point in the original grid has to span 360 degrees.

Parameters

[out]	gp	An array of grid positions.
[in]	old_grid	Original grid.
[in]	new_grid	New grid.
[in]	order	Interpolation order. 1 = linear, 2 = quadratic, etc.. The number of points used in the interpolation will be order+1.
[in]	extpolfac	Extrapolation fraction. Should normally not be specified, then the default of 0.5 is used.

		const Numeric &	extpolfac
	)

Set up grid positions for higher order interpolation on longitudes.

This function performs the same task as gridpos, but for arbitrary orders of interpolation. It is especially for interpolation of longitudes. If necessary, it will shift the given longitudes up or down by 360 degrees. For a global longitude grid, it will do cyclic interpolation.

The formula for calculating the weights w is taken from Numerical Recipes, 2nd edition, section 3.1, eq. 3.1.1.

Parameters

[in]	error_msg	Message for potential runtime error
[out]	gp	An array of grid positions.
[in]	old_grid	Original grid.
[in]	new_grid	New grid.
[in]	order	Interpolation order. 1 = linear, 2 = quadratic, etc.. The number of points used in the interpolation will be order+1.

	)

Interpolate 6D field to another 6D field.

This performs a "green" type interpolation of the field, that means that the grid position Arrays are interpreted as defining the grids for the interpolated field.

This function can be easily distinguished from the other interpolation function (that creates a sequence of interpolated values), because of the dimension of ia and itw.

The size of ia and itw in all dimensions must be consistent with the grid position Arrays.

Return values

ia	Interpolated field.

Parameters

itw	Interpolation weights.
a	The field to interpolate.
vgp	The grid position Array for the vitrine dimension.
sgp	The grid position Array for the shelf dimension.
bgp	The grid position Array for the book dimension.
pgp	The grid position Array for the page dimension.
rgp	The grid position Array for the row dimension.
cgp	The grid position Array for the column dimension.

Interpolate 2D field to a sequence of positions.

This performs a "blue" type interpolation of the field, that means that the grid position Arrays are interpreted as defining a sequence of positions. ALL GRID POSITION ARRAYS MUST HAVE THE SAME LENGTH!

The output vector ia also must have the same length. And the dimension of itw must be consistent with this.
