genident

Create an unused identifier

Use only in the MuPAD Notebook Interface.

This functionality does not run in MATLAB.

Syntax

genident()
genident(S)

Description

genident() creates an identifier not used before in the current session.

genident() creates an identifier with a name of the form Xi, where i is a positive integer. It is guaranteed that the returned identifier has not been used before in the current MuPAD® session.

If a stringS is given as argument, then genident returns an identifier with a name of the form Si, where i is a positive integer.

The returned identifier does not have a value.

Examples

Example 1

We create three new identifiers. The second identifier has a different prefix:

genident(), genident("Y"), genident()

In the next example, we assign a value to the identifier X4. Then the next two calls to genident skip the name X4:

X4 := 5:
genident(), genident()

Parameters

S

A character string

Return Values

identifier.
