Solution Number: 1-1B0WE
Date Last Modified: 23 Feb 2007

Product:		Symbolic Math Toolbox
Reported in Release:		R13sp1
Fixed in Release:
Platform:		All Platforms
Operating System:		All OS

  
Subject:Why do I receive the error message "??? Maple initialization failed." when using the Symbolic Math Toolbox 3.0.1 (R13SP1)?
Problem Description:Whenever I use any symbolic command, I recieve an error message.

For example,
syms x y
z = x+y
which produces the error message:
error_msg : socket 1820 listen failed (err=10022).

??? Maple initialization failed.
and will generate the following segementation violation:

Solution:All the Symbolic Toolbox functions call the Maple kernel, which is supported by Maplesoft, Inc. This problem is caused by the issue described at Maplesoft's support page at the following URL: http://www.maplesoft.com/support/Maple8/Installation/9.aspx Note that this solution refers to the "maplew8.exe" file which, in MATLAB, is built into the "matlab.exe" file. In addition, please note the paragraph stating that "Most personal firewall programs report that the [MATLAB] executable requires network access. This is somewhat misleading since the [MATLAB] executable is communicating with the mserver executable strictly on the local machine (through a TCP/IP connection)." Therefore, no information is actually sent through the internet. This behavior only occurs when using Maple 8. Maple 8 was used in the Symbolic Math Toolbox 3.0 and later. You can determine which Symbolic version you are using by typing ver symbolic at the MATLAB Command Prompt.
