bilinear_uniform: Bilinear Uniform Interpolator

In boostmath: 'R' Bindings for the 'Boost' Math Functions

Bilinear Uniform Interpolator

Description

Constructs a bilinear uniform interpolator given a grid of data points.

Usage

bilinear_uniform(x, rows, cols, dx = 1, dy = 1, x0 = 0, y0 = 0)

Arguments

x	Numeric vector of all grid elements
rows	Integer representing the number of rows in the grid
cols	Integer representing the number of columns in the grid
dx	Numeric value representing the spacing between grid points in the x-direction, defaults to 1
dy	Numeric value representing the spacing between grid points in the y-direction, defaults to 1
x0	Numeric value representing the x-coordinate of the origin, defaults to 0
y0	Numeric value representing the y-coordinate of the origin, defaults to 0

Value

An object of class bilinear_uniform with methods:

• interpolate(xi, yi): Evaluate the interpolator at point ⁠(xi, yi)⁠.

Examples

x <- seq(0, 1, length.out = 10)
interpolator <- bilinear_uniform(x, rows = 2, cols = 5)
xi <- 0.5
yi <- 0.5
interpolator$interpolate(xi, yi)
