Writing the M-file

The first step is writing the MATLAB M-file that you want to share. For this example, write a simple application that

takes a filename and a String and writes the String out to a file with the given name. This application consists of the

following lines:

% write the variable whatToWrite to a file called filename in the current

directory

fid = fopen(filename,'w');

fprintf(fid,'#writing to a file\n\n');

fprintf(fid,whatToWrite);

fclose(fid);

Compile the M-file

Within the MATLAB environment, call the MATLAB Compiler to convert this function into an application:

>> mcc -m writeToFile

Within the current working directory, this creates a number of files, including the following:

● writeToFile.exe (Windows) or

writeToFile (Linux, Mac OS X)

● writeToFile.ctf

Note: To use the MATLAB compiler on Mac OS X, you must have Xcode 2.2 installed; minimally, the Developer

Tools, gcc 4.0, gcc 3.3, Mac OS X SDK, and BSD SDK. These instructions were tested using Xcode 2.2.1.

Prepare the GenePattern Server

Install the MATLAB Component Runtime (MCR) on the GenePattern server, if you have not done so already. If the

GenePattern server has MATLAB installed, it also has the MCR installed.

Windows

To install the MCR:

1. Copy

<matlabroot>\toolbox\compiler\deploy\win32\MRCInstaller.exe to the

GenePattern server machine.

2. At the DOS prompt, or from Windows Explorer, run the following:

MCRInstaller.exe

Linux or Mac OS X

To install the MCR:

1. Within the MATLAB environment, create the MCRInstaller zip file:

>> buildmcr mcrdir

This creates a directory, mcrdir, beneath the current working directory and creates a file within that directory

called

MCRInstaller.zip.
