Communications Blockset™

saveas_commblks

Save Communications Blockset™ model using blocks of earlier version

Syntax

flag = saveas_commblks(sys,new_sys,version)

Description

Note   This function is obsolete. Simulink® software provides a similar functionality through its Save As... option in the File menu of its models.

saveas_commblks is designed to replace Communications Blockset R14SP2 (version 3.1) blocks with R14 (version 3.0) or R14SP1 (version 3.0.1) blocks.

flag = saveas_commblks(sys,new_sys,version) saves the model sys to a previous version specified by version, with the name new_sys. version must be either R14 or R14SP1. flag is true if the operation is successful, else it is false. It displays the list of blocks that are updated in the command window.

saveas_commblks updates the following blocks in the model:

• AWGN Channel

• Binary Symmetric Channel

• Multipath Rician Fading Channel

• Voltage-Controlled Oscillator or Continuous-Time VCO

• All blocks from the AM sub-library of the Digital Baseband Modulation library (commdigbbndam3). These blocks are replaced by the corresponding blocks from the old AM library (commdigbbndam2).

• All blocks from the PM sub-library of the Digital Baseband Modulation library (commdigbbndpm3). These blocks are replaced by the corresponding blocks from the old PM library (commdigbbndpm2).

• Multipath Rayleigh Fading Channel block from the Channels library (commchan3). These blocks are replaced by the Multipath Rayleigh Fading Channel block from the old Channels library (commchan2). Note that the default parameters of this block are used after the model is saved.

Example

success = saveas_commblks('myCommsSystem','myCommsSystemR14sp1','R14SP1') saves the system myCommsSystem to one using the blocks in the R14SP1 version of Communications Blockset, and returns true on successful operation.
