MATLAB automatically generates C code

1. Prepare m file simpleproduct.m

function C = Simpleproduct (A, B)
C=a*b;

2. Enter coder in the MATLAB work interface and enter the project name Simpleproduct

3. Add the simpleproduct.m file to the project

4. Define the data type of the input variable A/b

5. Generate a MEX function to test whether the program is correct

6. Generate C code, tick generate code only

7. Under the codegen/lib/simpleproduct/of the current directory, you can see that a heap of. C and. h files are generated

$ ls codegen/lib/simpleproduct/
buildinfo.mat   rt_nonfinite.h               SIMPLEPRODUCT_REF.RSP
html             rtw_proj.tmw                 simpleproduct_rtw.mk
rtgetinf.c      rtwtypes.h                   simpleproduct_ TERMINATE.C
rtgetinf.h      simpleproduct.c              simpleproduct_terminate.h
rtgetnan.c      simpleproduct.h             SimpleProduct_types.h
rtgetnan.h      simpleproduct_initialize.c
rt_nonfinite.c  simpleProduct_ Initialize.h

8. Create a new C project, copy all the. C and. h files under codegen/lib/simpleproduct/to the project and create a new MAIN.C file with the following contents:

2. #include <stdlib.h>
4. #include <stdio.h>
6. #include "simpleProduct.h"
8. #include "simpleproduct_initialize.h"
10. #include "simpleproduct_terminate.h"
14. int Main ()
16. {
18. Simpleproduct_initialize ();
20. printf ("%lf", Simpleproduct (5,6));
22. Simpleproduct_terminate ();
24. return 0;
26. }

9. Compile the project and view the results of the operation
