### FUNCTION: ISOpure.util.matlab_greater_than.R ###########################################
# Change '>' to match the Matlab: when one of the values is NA or NaN,
# return false
#
# Input variables:
# a, b: two scalars
#
# Output variables:
# Logical: TRUE if a > b, FALSE if a <= b OR if one of a, b is NA or NaN
#
# REVISIT: should extend to vectors/matrices
ISOpure.util.matlab_greater_than <- function(a, b) {
# If either a or b is NA or NaN, output false, not NA
if (is.na(a) || is.na(b) || is.nan(a) || is.nan(b)){
output <- FALSE;
}
# otherwise R handles cases the same as Matlab (Inf, -Inf, etc.)
else {
output <- (a > b);
}
return(output);
