slupdate

Replace obsolete versions of blocks in a model with the latest versions

Syntax

• slupdate('sys')
  slupdate('sys', prompt)
  

Description

slupdate('sys') replaces versions of blocks in the model sys made obsolete by Simulink 5 with the latest versions. slupdate('sys', prompt)specifies whether to prompt you before replacing a block. If prompt equals 1, the command prompts you before replacing the block. The prompt asks whether you want to replace the block. Valid responses are

• y

• Replace the block (the default)

• n

• Do not replace the block

• a

• Replace this and all subsequent obsolete blocks without further prompting

If prompt equals 0, the command replaces all obsolete blocks without prompting you.

Note    The model to be updated must have been created by a version of Simulink earlier than Simulink 5 and must be open when you call slupdate.

Blocks updated by this command include:

Block	Comments
Pulse Generator	New implementation
Hit Crossing	S-function replaced by built-in implementation
Memory	S-function replaced by built-in implementation
Quantizer	S-function replaced by built-in implementation
Graph scope	Replaced by much-improved built-in Scope
2-D Table Lookup	S-function replaced by built-in implementation
Elementary Math	Replaced by either the Trigonometry, Rounding, or Math block
To Workspace	Three-element version of Maximum rows parameter is separated into individual fields
Outport	Replace initial output of width []

In addition to replacing obsolete blocks, slupdate

• Adds terminator blocks to any unconnected input and output ports, i.e., Ground and Terminator blocks, respectively
• Converts blocks to links in the appropriate block libraries
• Replaces any masked built-in block that is not a subsystem or S-functions with a masked subsystems containing the built-in block
