Hi Vikram,
Looks like you are facing an error running “mex ./getBADL_mx.c ../c/getBADL.c -I../c” in the MATLAB. You are facing an error of “unknown file extension”. You would also like to know the usage of “-I” flag and how it should be altered if you change your MATLAB path.
Here's a breakdown of the command you provided:
mex ./getBADL_mx.c ../c/getBADL.c -I../c
- “./getBADL_mx.c” and “../c/getBADL.c” are the source files for your “mex” function.
- “-I../c” specifies that the compiler should look for header files in the “../c” directory.
If you are encountering the error "Unknown file extension ' '," it's possible that there might be an issue with the paths or spaces in the paths. Make sure that there are no spaces in the paths to the source files or the include directory.
The “-I” flag in the “mex” command is used to specify an additional directory where the compiler should look for ”C/C++” header files. In your case, “-I../c” is telling the compiler to look for header files in the “../c” directory.
As for changing the MATLAB path, if you move your source files or change the directory structure, you need to update the paths accordingly. In your case, if the “getBADL_mx.c”, “getBADL.c”, and the “../c” directory are still in the same relative locations, you might not need to change anything. However, if the structure has changed, you'll need to adjust the paths accordingly.
For example, if you move the source files and the “../c” directory to a different location, you would need to update the paths in the “mex” command accordingly.
mex /new/path/to/getBADL_mx.c /new/path/to/getBADL.c -I/new/path/to/c
You can hit the command “mex -help” in the command window to know more about “-I” flag and many other flags associated with “mex”.
Please refer to the following documentation to learn more about using “mex”:
Hope it helps.
