Error Log Reporter Passing Perl Variables on Startup Startup and Calling Java Software from the MATLAB Program

Error Log Reporter

Upon startup, if the MATLAB program detects an error log generated by a serious problem encountered during the previous session, an Error Log Reporter prompts you to e-mail the log to The MathWorks for analysis. Click Send Report to e-mail the log, or click Help for more information. After sending the log, a confirmation message appears in the Command Window. For more information, see Abnormal Termination.

Passing Perl Variables on Startup

You can pass Perl variables to MATLAB on startup by using the -r option of the matlab function. For example, assume a MATLAB function test that takes one input variable:

function test(x)

To start MATLAB with the function test, use the command

matlab -r "test(10)"

On some platforms, you might need to use double quotation marks:

matlab -r "test(10)"

This command starts MATLAB and runs test with the input argument 10.

To pass a Perl variable instead of a constant as the input parameter, follow these steps.

1. Create a Perl script such as

    #!/usr/local/bin/perl
    $val = 10; 
    system('matlab -r "test(' . ${val} . ')"');

2. Invoke the Perl script at the prompt using a Perl interpreter.

For more information, see the matlab (Windows) or matlab (UNIX) reference page.

Startup and Calling Java Software from the MATLAB Program

When the MATLAB program starts, it constructs the class path for Sun Microsystems Java software using librarypath.txt as well as classpath.txt. If you call Java software from MATLAB, see more about this in The Java Class Path and Locating Native Method Libraries in the MATLAB External Interfaces documentation.
