施用php在网页执行matlab

使用php在网页执行matlab

通过php调用linux命令,可以实现远程调用matlab.

试验环境:Fedora16, matlab2012b linux version, Google chrome 18.0.1025.108 beta

以下代码实现了在网页输入matlab命令并显示执行结果。注意：如果不加-nodisplay选项，会出现" no display specified"的警告，当然可以在执行matlab命令之前unset DISPLAY也可以直接在terminal执行matlab。

如果你仅仅想远程调用matlab函数，可以参考mathworks的php webservice相关文档，此处也可以参考官方关于python调用的文档。

以下代码对于plot()等绘图命令会出现{Warning: Objects of graph2d.lineseries class exist - not clearing this class or any of its super-classes}错误，目前未解决（也就是无法绘图）。但是通过ssh远程登陆服务器调用相同命令可以plot并save图像，不解。

输入sin(1:10)进行简单计算

输入ver命令获取版本信息

直接终端运行

mathwork关于matlab启动参数的介绍：

SpecifyingMATLAB Startup Options

Youcan specify startup options (also called command flags or commandline switches) that instruct the MATLAB program to perform certainoperations when you start it. On all platforms, you specify theoptions as arguments to the matlab command when you start is at theoperating system prompt. For example, the following starts MATLAB andsuppresses the display of the splash screen.

matlab-nosplash

OnWindows platforms, you can precede a startup option with either ahyphen (-) or a slash (/). For example, -nosplash and /nosplash areequivalent.

Onall platforms, you can also specify startup options using a MATLABstartup file—see Specifying Startup Options in the MATLAB StartupFile

OnWindows platforms, you can specify startup options in the MATLABshortcut—see Including Startup Options in a Shortcut on WindowsSystems.

IncludingStartup Options in a Shortcut on Windows Systems

Youcan add selected startup options (also called command flags orswitches for the command line) to the target path for your shortcutin the Windows environment for MATLAB. For more information about theoptions, see CommonlyUsed Startup Options.

Touse startup options for the MATLAB shortcut icon in a Windowsenvironment, follow these steps:

1. Right-clickthe shortcut icon for MATLAB  andselect Properties from the context menu. TheProperties dialog box for MATLAB opens to the Shortcut pane.

2. Inthe Target field,after the target path for matlab.exe,add the startup option, and click OK.For example, adding -r"filename" runsthe MATLAB code file filenameafterstartup.

Thisexample instructs MATLAB to automatically run the file results afterstartup, whereresults.m isin the startup folder or on the search path for MATLAB. The statementin the Target fieldmight appear as

<span style="color:#000000"><span style="font-family:courier new,courier,monospace">C:\Program Files\MATLAB\R2010b\bin\matlab.exe -r "results"</span></span>

Includethe statement in double quotation marks ("statement").Use only the file name, not the file extension or path name. Forexample, MATLAB produces an error when you run

<span style="color:#000000"><span style="font-family:courier new,courier,monospace">... matlab.exe -r "D:\results.m"</span></span>

Usesemicolons or commas to separate multiple statements. This examplechanges the format to short,and then runs the MATLAB code file results:

<span style="color:#000000"><span style="font-family:courier new,courier,monospace">... matlab.exe -r "format('short');results"</span></span>

Separatemultiple options with spaces. This example starts MATLAB withoutdisplaying the splash screen, and then runs the MATLAB codefile results:

<span style="color:#000000"><span style="font-family:courier new,courier,monospace">... matlab.exe -nosplash -r "results"</span></span>

SpecifyingStartup Options in the MATLAB Startup File

Atstartup, MATLAB automatically executes the file matlabrc.m and,if it exists,startup.m.The file matlabrc.m,which is in the matlabroot/toolbox/local folder,is reserved for use by MathWorks and by the system manager onmultiuser systems.

Thefile startup.m isfor you to specify startup options. For example, you can modify thedefault search path, predefine variables in your workspace, or definedefaults for Handle Graphics? objects.Use the following statements in a startup.m fileto add the specified folder, /home/username/mytools,to the search path, and to change the current folder to mytools uponstartup.

<span style="font-family:DejaVu Sans Mono,monospace"><span style="font-family:'courier new',courier,monospace"><span style="font-size:9pt">addpath /home/</span></span><tt class="western"><span style="font-family:'courier new',courier,monospace"><span style="font-size:9pt"><em>username</em></span></span></tt><span style="font-family:'courier new',courier,monospace"><span style="font-size:9pt">/mytools</span></span></span><span style="font-family:DejaVu Sans Mono,monospace"><span style="font-family:'courier new',courier,monospace"><span style="font-size:9pt">cd /home/</span></span><tt class="western"><span style="font-family:'courier new',courier,monospace"><span style="font-size:9pt"><em>username</em></span></span></tt><span style="font-family:'courier new',courier,monospace"><span style="font-size:9pt">/mytools</span></span></span>

<span style="font-size:9pt; font-family:'Times New Roman',serif"><span style="font-family:Verdana,Arial,Helvetica,sans-serif"><span style="font-size:9pt">Placethe </span></span></span><tt class="western" style="font-size:9pt"><span style="font-family:'courier new',courier,monospace"><span style="font-size:9pt">startup.m</span></span></tt><span style="font-size:9pt; font-family:'Times New Roman',serif"><span style="font-family:Verdana,Arial,Helvetica,sans-serif"><span style="font-size:9pt"> filein the default or current startup folder, which is where MATLAB firstlooks for it. For more information, see .</span></span></span>

CommonlyUsed Startup Options

Thefollowing table provides a list of some commonly used startup optionsfor both Windows and UNIX? platforms.For more information, including a complete list of startup options,see the matlab(Windows) referencepage or the matlab(UNIX) referencepage.

PassingPerl Variables on Startup

Youcan pass Perl variables to MATLAB on startup by usingthe -r optionof the matlabfunction.For example, assume a MATLAB function test thattakes one input variable:

<span style="color:#000000"><span style="font-family:courier new,courier,monospace">function test(x)</span></span>

Tostart MATLAB with the function test,use the command

<span style="color:#000000"><span style="font-family:courier new,courier,monospace">matlab -r "test(10)"</span></span>

Onsome platforms, you might need to use double quotation marks:

<span style="color:#000000"><span style="font-family:courier new,courier,monospace">matlab -r "test(10)"</span></span>

Thiscommand starts MATLAB and runs test withthe input argument 10.

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

1. Createa Perl script such as

   <span style="color:#000000"> <span style="font-family:DejaVu Sans Mono,monospace"><span style="font-family:courier new,courier,monospace"><span style="font-size:12px; font-size:9pt">#!/usr/local/bin/perl</span></span></span></span><span style="color:#000000"> <span style="font-family:DejaVu Sans Mono,monospace"><span style="font-family:courier new,courier,monospace"><span style="font-size:12px; font-size:9pt">$val = 10; </span></span></span></span><span style="color:#000000"> <span style="font-family:DejaVu Sans Mono,monospace"><span style="font-family:courier new,courier,monospace"><span style="font-size:12px; font-size:9pt">system('matlab -r "test(' . ${val} . ')"');</span></span></span></span>

   Copy after login

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

Formore information, see the matlab(Windows) or matlab(UNIX) referencepage.

Startupand Calling Java Software from the MATLAB Program

Whenthe MATLAB program starts, it constructs the class path for SunMicrosystems Java software using librarypath.txt aswell as classpath.txt.If you call Java software from MATLAB, see more about this in TheJava Class Path and LocatingNative Method Libraries inthe MATLAB External Interfaces documentation.
