I want to run coda by MATLAB interface. When I mex coda\_matlab.c, following error, displayed:
fatal error: coda.h: No such file or directory.
Please let me know what should I do?

The MATLAB interface of CODA is not meant to be build using the matlab mex script.
You need to enable the MATLAB interface when you build CODA from source. See the installation instructions for details.
Note that for Windows the MATLAB interface is already included in the binary installer.
