What are the application of matlab?

Answer 1

To Compile or Not to Compile

There are several cases where compiling your code can be advantageous: If you want to distribute your code to people that have no Matlab installed, If you want to run a large number of Matlab jobs simultaneously on a computing cluster, you are usually limited by the number of licenses available. Working with a compiled standalone version, not requiring a Matlab license, provides a nice workaround. If your Matlab is using your institute's license server, it might happen that no licenses are available anymore. If you have your Matlab code and you are to run

several paparmatric studies, then a standalone version might bring help, since you are not dependent anymore on the availability of the licenses on the license server. This might require some minor re-thinking and re-writing of your program to let it behave as a general-purpose program (read some parameters, read the input data and start the calculations).

After creating your component with the MATLAB Compiler, you can distribute, or deploy, it to others so that they can use it on their machines, independent of MATLAB.

The deployment process requires that you: Package the necessary components depending on the type of generated application. Distribute them to your end user. Have the end users install them on their systems. During this phase of the installation process, the end users run MCRInstaller once on their target machine, that is, the machine where they will run the application or library. On Windows, MCRInstaller is a self-extracting executable that installs thenecessary components to run your application. On UNIX, MCRInstaller is a ZIP file.

The compiling/packaging process

Step 0:

Before using the Matlab Compiler for the first time, you must run the setup command on mbuild to configure your C/C++ compiler to work with the Matlab Compiler. (The Matlab Compiler requires a supported ANSI C or C++ compiler installed on your system.). This setup step is only to be performed once.

>> mbuild -setup

Please choose your compiler for building standalone MATLAB applications:

Would you like mbuild to locate installed compilers [y]/n?

Select a compiler:

[1] Lcc C version 2.4.1 in C:\PROGRAM FILES\MATLAB71\sys\lcc

ICTS/FOOCES

Compiler_3

[2] Microsoft Visual C/C++ version 7.1 in C:\Program Files\Microsoft Visual Studio .NET 2003

[0] None

Depending on the compilers installed on your system, you can select one. The Lcc compiler is installed by default when installing the Compiler Toolbox.

A very simple program is used to demonstrate the compiler/deploytool

Compiling the code

Remark: older version of the compiler might have problems when compiling script M-files Instead, they must be converted into function M-files. Normally, this is simply a case of wrapping the main section of code within a function. type deploytool to open the Deployment Tool window. The Deployment Tool opens as a dockable window in the MATLAB desktop, and a menu labeled Project is added to the MATLAB menu bar.

Create a new project:

o In the Deployment Tool toolbar, click the New Project icon.

o In the New Deployment Project dialog box, select (Windows) Standalone Applications, and enter the following settings (The Matlab Compiler deployment target "Windows Standalone Application" was new with Matlab R2007b. Older versions only had the "Standalone Application" option - the difference being the new Windows Standalone Application does not start a command console (dos box)):

 In the Name field, enter the project name.

 In the Location field, enter the name of your work directory

 Click OK.

The MATLAB Compiler displays the project folder in the Deployment Tool window. The folder contains three folders, which are empty.

o Drag the main routine of your Matlab program to the Main function folder.

o If other files are included in your programming project, drag then to the Other files folder.

In the screendump below, an example is shown with the main program (TSP_v1_func.m) and all the functions that are called by this main function are placed under 'Other files')
