## Is MATLAB compatible with Windows 7?

While unsupported, some earlier versions of MATLAB may still run on Windows 7. In order to install an earlier release, you may have to run the installer in compatibility mode for a previous version of Windows. Set this field to “Windows Vista” or “Windows XP”.

**What is MEX command in MATLAB?**

A MEX file is a function, created in MATLAB, that calls a C/C++ program or a Fortran subroutine. A MEX function behaves just like a MATLAB script or function. To call a MEX function, use the name of the MEX file, without the file extension. The MEX file contains only one function or subroutine.

**What is MEX setup MATLAB?**

MATLAB displays a message with links to select a different default compiler. If you call mex -setup without the lang argument, then MATLAB displays information about the default C compiler. MATLAB also displays links to the other supported languages. To change the default for another language, select a link.

### Is MEX faster than MATLAB?

This is c file to calculate matrix-vector product using mex file. According to the data, we can see c-compiler is much faster than matlab, matlab using mex file is too slow comparing to the others.

**How much RAM do I need for MATLAB?**

4 GB RAM

Minimum of 4 GB RAM per MATLAB worker is recommended. If you are using Simulink, 8GB RAM per worker is recommended.

**Do I need a graphics card for MATLAB?**

Graphics. No specific graphics card is required. Hardware accelerated graphics card supporting OpenGL 3.3 with 1GB GPU memory is recommended. GPU acceleration using Parallel Computing Toolbox requires a GPU that has a compute capability 3.0 or higher.

#### What is Mex code?

From Wikipedia, the free encyclopedia. A MEX file is a type of computer file that provides an interface between MATLAB or Octave and functions written in C, C++ or Fortran. It stands for “MATLAB executable”.

**How do I open a MEX file?**

Depending on your operating system, you will right-click on the MEX file, select “Open With” and select either MATLAB Macintosh Dynamically Linked Subroutines, WordPerfect Macro Editor Expound File, mexReader Multimedia File, or a similar software program from the installed programs on your PC.

**How do I use a MEX file?**

To call a MEX file, put the file on your MATLAB® path. Then type the name of the file, without the file extension. If you have MEX file source code, see Build C MEX Function for information about creating the executable function.

## How do I create a C++ MEX file in MATLAB?

Create a C++ MEX Source File

- Create Source File. Using your editor, create a file with a .
- Add Required Header Files. For C++ MEX functions, add these header files.
- Using Convenience Definitions.
- Define MexFunction Class.
- Define operator()
- Add Member Function to Check Arguments.
- Implement Computation.
- Call MEX Function.

**What is Matlab Coder?**

MATLAB Coder™ generates C and C++ code from MATLAB® code for a variety of hardware platforms, from desktop systems to embedded hardware. It supports most of the MATLAB language and a wide range of toolboxes. You can integrate the generated code into your projects as source code, static libraries, or dynamic libraries.

**Is 16 GB RAM enough for MATLAB?**

Cluster Computers Running MATLAB Workers (All Schedulers) Minimum of 4 GB RAM per MATLAB worker is recommended. Approximately 32GB of disk space to accommodate a typical complete installation of MATLAB Parallel Server. Complete installation of MATLAB Parallel Server will also install MATLAB, Simulink, and Toolboxes.
