Fast implementation of pracma::trapz from the Armadillo C++ library

Description

Compute the area of a multivariate function with (matrix) values Y at the points x.

Usage

fastTrapz(x, Y, dim = 1L)

Arguments

x	x-coordinates of points on the x-axis (vector)
Y	y-coordinates of function values (matrix)
dim	an integer giving the subscripts which the function will be applied over. 1 indicates rows, 2 indicates columns

Value

a vector with one dimension less than Y

Examples

x = 1:10
Y = sin(pi/10*matrix(1:10,ncol=10,nrow=10))
fastTrapz(x*pi/10,Y,2)
