MATLAB: Are all the libraries that Real-Time Workshop links when it builds a model necessary to run the model as a standalone application

buildnecessaryprocessrealsimulink codertime

I am searching for ways to reduce the size of the generated executable and related files needed to run a model as a standalone module. If I look at the make file that is generated in the Real-Time Workshop build directory, I see that a large number of libraries are being linked to create the executable from the model. I wanted to know that if all these libraries are essential to running the model, or all libraries are linked irrespective of whether they are needed.

Best Answer

Real-Time Workshop links in only the necessary libraries when building the model.

MATLAB: How to locate the source code Real-Time Workshop uses to generate and compile code for various algorithms used in the blocks in the model

The makefile that Real-Time Workshop generates for a model contains information about the source files that are included in the compilation process for building the executable for a particular model.

To find the code that implements an algorithm, search for a function in the source files that are included by the model's makefile.

Consider the following example, which is based on Real-Time Workshop 6.2 (R14SP2).

1. Open the model lmsdemo.mdl, by typing the following MATLAB command at the command prompt:

lmsdemo

2. Set the system target file to grt.tlc (Visual C/C++ Project makefile only for the "grt" target).

3. Select "Generate Code only" and click on "Generate Code" button.

Real-Time Workshop generates the file lmsdemo.c and places it in the directory "lmsdemo_grt_rtw".

4. Open lmsdemo.c source file.

5. Find the function named "MWDSP_lmsn_ay_wy_DD". This function implements the LMS algorithm. The source code for this algorithm is in the file lmsn_ay_wy_dd_rt.c, which is in the directory $MATLABROOT\toolbox\rtw\dspblks\c\dsplms. The makefile lmsdemo.mak (in the "lmsdemo_grt_rtw" directory) contains information about all the files Real-Time Workshop uses to compile the code generated for the model.

For example, the following line of code appears in the makefile lmsdemo.mak (generated for lmsdemo.mdl). This line shows that lmsn_ay_wy_dd_rt.c is included during compilation of the code for the model.

 SOURCE=D:\Applications\MATLAB704\toolbox\rtw\dspblks\c\dsplms\lmsn_an_wy_dd_rt.c

MATLAB: In what library is the “rtInf” variable located under Real-Time Workshop

We have verified that the Real-Time Workshop documentation does not identify the location of the "rtInf" variable.

Depending on the version of Real-Time Workshop you are using, you can find the “rtInf” variable in the following files.

If you are using Real-Time Workshop 5.0 (R13) or Real-Time Workshop 5.1 (R13SP1), see rt_nonfinite.h and rt_nonfinite.c in $MATLAB/rtw/c/src

(where $MATLAB is the root directory of your MATLAB installation).

If you are using Real-Time Workshop 6.0 (R14) or later, see rt_nonfinite.h, rt_nonfinite.c in the project directory (model_grt_rtw).
