reverse

 

 

Description

The reverse function creates and returns a new Matrix, which contains the elements of the argument {obj} in reverse order. The argument {obj} may be a proper List or a Matrix.

When to use

Note: Returns an error message if the Matrix is not of rank one.

Use the reverse function reorganizes the elements in a Matrix in reverse order.

 

Syntax

(reverse obj)



Name Description AIS Types
objMust be a Matrix Matrix


Returns:

Returns a Matrix containing the elements in reverse order

 

Examples

Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

Example_Matrix_reverse_002

These examples use the reverse function to rearrange the elements of the Matrix. The Matrix, with its elements in reverse order is returned.

 

Argument Types

Here are the links to the data types of the function arguments.

List Vector Matrix NumMatrix
FltVector ShortVector IntVector NumVector
ObjVector BitVector

Here are also a number of links to functions having arguments with any of these data types.
