omxLogical {OpenMx} R Documentation

## Logical mxAlgebra() operators

### Description

omxNot computes the unary negation of the values of a matrix. omxAnd computes the binary and of two matrices. omxOr computes the binary or of two matrices. omxGreaterThan computes a binary greater than of two matrices. omxLessThan computes the binary less than of two matrices. omxApproxEquals computes a binary equals within a specified epsilon of two matrices.

### Usage

omxNot(x)
omxAnd(x, y)
omxOr(x, y)
omxGreaterThan(x, y)
omxLessThan(x, y)
omxApproxEquals(x, y, epsilon)


### Arguments

 x the first argument, the matrix which the logical operation will be applied to. y the second argument, applicable to binary functions. epsilon the third argument, specifies the error threshold for omxApproxEquals. Abs(x[i][j]-y[i][j]) must be less than epsilon[i][j].

### Examples

A <- mxMatrix(values = runif(25), nrow = 5, ncol = 5, name = 'A')
B <- mxMatrix(values = runif(25), nrow = 5, ncol = 5, name = 'B')
EPSILON <- mxMatrix(values = 0.04*1:25, nrow = 5, ncol = 5, name = "EPSILON")

model <- mxModel(A, B, EPSILON, name = 'model')

mxEval(omxNot(A), model)
mxEval(omxGreaterThan(A,B), model)
mxEval(omxLessThan(B,A), model)
mxEval(omxOr(omxNot(A),B), model)
mxEval(omxAnd(omxNot(B), A), model)
mxEval(omxApproxEquals(A,B, EPSILON), model)
