matinterp: Matrix Linear Interpolator

In floswald/GSLtools: What the package does (short line)

Description

takes 2 matrices Y and Xi, and a grid x. x and Y are original function values on x and Xi are new points at which to evaluate the function. Linear Interpolation.

Usage

  matinterp(x, Y, Xi)

Arguments

x	grid on which Y=f(x) defined
Y	matrix of funciton values. each row is a different function defined on same grid.
Xi	matrix of new grid values at which to obtain Xi = f(Yi).

Examples

x <- seq(0,1,le=10)
Y <- log(outer(1:5,x,"+"))
Xi <- matrix(seq(0.1,0.99,le=12),5,12,byrow=T)
res <- matinterp(x,Y,Xi)
