omxCheckCloseEnough: Approximate Equality Testing Function

In OpenMx: Extended Structural Equation Modelling

Approximate Equality Testing Function

Description

This function tests whether two numeric vectors or matrixes are approximately equal to one another, within a specified threshold.

Usage

omxCheckCloseEnough(a, b, epsilon = 10^(-15))

Arguments

a	a numeric vector or matrix
b	a numeric vector or matrix
epsilon	a non-negative tolerance threshold

Details

Arguments ‘a’ and ‘b’ must be of the same type, ie. they must be either vectors of equal dimension or matrices of equal dimension. The two arguments are compared element-wise for approximate equality. If the absolute value of the difference of any two values is greater than the threshold, then an error will be thrown.
