从Wamp服务器执行但不是命令提示符时，Matlab返回许可证检出错误(Matlab returns license checkout error when executed from Wamp server but not command prompt)

我在Windows 7 SP1 64位计算机上运行WAMP Server 2.5（32位）和PHP 5.5.12。 我正在运行Matlab R2014b。

我试图通过PHP执行Matlab。

Matlab函数phptest.m如下：

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

当我从命令提示符执行时：

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

代码运行没有问题，并创建文件'sucess.txt'。

但是，如果我尝试通过php文件执行：

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

日志文件显示以下错误：

严重：检查许可证时出错

任何帮助，将不胜感激。

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.

最满意答案

您可以通过使用-c标志运行MATLAB来强制使用特定的许可证文件：

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

matlab -c licensefile使用指定的许可证文件启动MATLAB。 licensefile参数可以具有port @ host形式，也可以是以冒号分隔的许可证文件名列表。 此选项会导致忽略LM_LICENSE_FILE和MLM_LICENSE_FILE环境变量。

请参阅： http ： //www.mathworks.nl/help/matlab/ref/matlabwindows.html

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.
