Difference between Simulink Coder, Embedded Coder and Matlab Coder

Hi,

Please carify me the difference between the Simulink Coder, Embedded Coder and the Matlab Coder.

Also please share any documents on the above products.

Thank you Praveen

Answer 1

[Arnaud Miege]

MATLAB Coder is used to generate ANSI C/C++ code from MATLAB and is a pre-requisite for Simulink Coder and Embedded Coder. Simulink Coder does the same thing, but from Simulink. Embedded Coder allows to optimize/customize the code generated by MATLAB Coder and Simulink Coder for production use.

Have a look at this blog for more information.

HTH,

Arnaud

Hi, here is an example between Simulink Coder and Embedded Coder:

open_system('rtwdemo_slcustcode')

If someone would like to explain, please, be my welcome guest. I've notives that Embedded Coder generates less code .c and .h than Simulink Coder. But, what is really the difference?

Best!

Hi,

I think the product discription on the hompage explains it very good:

[ROGER LAHOUD]

no it doesnt

[joe farmer]

I agree. Don't RTFM us Fartrich on 21 Jul 2011!!

Thanks @Friedrich, the links are great, they tell it all:

• "MATLAB Coder™ generates C and C++ code from MATLAB® code for a variety of hardware platforms..."
• "Simulink Coder™ (formerly Real-Time Workshop®) generates and executes C and C++ code from Simulink® models..."
• "Embedded Coder extends MATLAB Coder™ and Simulink Coder™ with advanced optimizations for precise control of the generated functions, files, and data..."

hi If I want to share a block simulink or embedded function That I have created. Can I send it like a black box to someone in order to keep it secret from other users. (I do not want to use S-function or mask) thanks

As others have mentioned:

• MATLAB Coder enables users to generate C/C++ code from MATLAB algorithms
• Simulink Coder does the same for Simulink models
• Finally, Embedded Coder is an add-on to either MATLAB Coder or Simulink and unlocks additional code optimization, verification, and targeting capabilities (such as PIL)

For those interested, you can find a list of additional capabilities that Embedded Coder adds to MATLAB Coder here:

From historical perceptive:

In the 1980s, it was only Matlab and it was interpeted, that is slower than a compiled code, so they provided a tool to convert m-files to C files and LCC to compile the C code to executable, which was called Mex file.

Then, in the 1990s, Simulink appeared and for the same reason, a conversion to C files were provided with LCC.

People started using this tool chain, as they have a nice diagram (Simulink) and the corresponding auto-generated code running on various targets, so Mathworks started support it, hence Embedded Coder was born.
