 RemoveInRange - Maple Help

Statistics

 SelectInRange
 select data items in a given range
 RemoveInRange
 remove data items in a given range Calling Sequence SelectInRange(X, R, options) RemoveInRange(X, R, options) Parameters

 X - R - data range options - (optional) equation of the form include=value Description

 • The SelectInRange function selects all items from X which belong to the specified range R and returns them in a new data sample with the same options as X.
 • The first parameter X is a data sample - given as e.g. a Vector.
 • The second parameter R is the range. By default the range R is considered closed from the left and open from the right. This can be changed using the include option.
 • The RemoveInRange function does the opposite of SelectInRange. It removes all data items from X which belong to the range R. Options

 The options argument can contain the following option:
 • include=left, right or [left, right] -- Specify whether the endpoints should be included in the interval. By default, the interval defined by R is considered closed on the left and open on the right. Notes

 • Each element of X can be any Maple expression, but this expression must be able to be evaluated to a floating-point number. Failure to do so will generate an error.
 • The SelectInRange and RemoveInRange commands leave the original data set X unchanged. Examples
