从Wamp服务器执行时，Matlab返回许可证检出错误，但不是命令提示符

Question

I am running WAMP Server 2.5 (32-bit) with PHP 5.5.12 on a Windows 7 SP1 64-bit machine. I am running Matlab R2014b.

I am trying to execute Matlab via PHP.

The Matlab function phptest.m is as follow:

function phptest
% Open file
fid = fopen('success.txt', 'wt');
%Print a test string
fprintf(fid, 'Test matlab function');
% Close file
fclose(fid);
% Quit MATLAB
quit force

When I execute from the command prompt:

matlab -wait -nosplash -sd "C:\wamp\www\testMatlab" -logfile logfile.txt -r "phptest;"

the code runs without problems and the file 'sucess.txt' is created.

However, if I try to execute via a php file:

<?php
$testStr = 'matlab -wait -nosplash -sd "C:\wamp\www\testMatlab" -logfile logfile.txt -r "phptest;"';
exec($testStr);
echo("Done!");
?>

The logfile shows the following error:

Severe: Error checking out license

Any help would be appreciated.

Answer 1

You can force MATLAB to use a specific license file by running it with the -c flag:

'matlab -c "path/to/license" -wait -nosplash -sd "C:\wamp\www\testMatlab" -logfile logfile.txt -r "phptest;"';

matlab -c licensefile starts MATLAB using the specified license file. The licensefile argument can have the form port@host or it can be a colon-separated list of license filenames. This option causes the LM_LICENSE_FILE and MLM_LICENSE_FILE environment variables to be ignored.
