Math
result = between(lowerbound, argument, upperbound, gtstrict=gtstrict, ltstrict=ltstrict)
Determines if the argument lies between the bounds.
Return value
Outputs 1 for any element where Argument is between Lowerbound and Upperbound, and 0 for all other elements. Values equal to Lowerbound and Upperbound return 1 unless overridden by /GTSTRICT and/or /LTSTRICT. Each of the inputs may be either a scalar or an array, but if more than one are arrays then they must have the same numbers of elements.
Parameters
- lowerbound in
Scalar or array of lower bounds.
- argument in
Scalar or array of numerical argument.
- upperbound in
Scalar or array of upper bounds.
Keywords
- gtstrict in
Argument must be strictly greater than Lowerbound, rather than greater or equal to.
- ltstrict in
Argument must be strictly less than Upperbound, rather than less or equal to.
