3Calling C and Fortran Programs from MATLABAlthough MATLAB is a complete, self-contained environment for programming and manipulating data, it is often useful to interact with data and Programs external to the MATLAB environment. MATLAB provides an interface to external Programs written in the C and Fortran languages.
