Call MATLAB Functions from C Applications - MATLAB & Simulink (original) (raw)
Main Content
The program engdemo.c in the_matlabroot_/extern/examples/eng_mat folder illustrates how to call the engine functions from a standalone C program. This example uses the C Matrix API.
For a Microsoft® Windows® version of this program, open engwindemo.c in the_matlabroot_\extern\examples\eng_mat folder. For a C++ version, open engdemo.cpp.
The first part of this program starts MATLAB and sends it data. MATLAB analyzes the data and plots the results.
The program continues with:
Pressing Return continues the program:
Done for Part I. Enter a MATLAB command to evaluate. This command should create a variable X. This program will then determine what kind of variable you created. For example: X = 1:5
Entering X = 17.5 continues the program execution.
X = 17.5
X =
17.5000
Retrieving X... X is class double Done!
Finally, the program frees memory, closes the MATLAB engine, and exits.
