Matlab C++ External Interface Routines

摘要

Matlab is a flexible computing environment for creating, exploring, and visualizing data and algorithms. It is available for several platforms including Windows, Linux, Solaris, Macintosh, AIX, and more. The Matlab language, on the other hand, is a high-level language that lets you perform complex operations with a few lines of code. Of course, the trade-off for this power is that some operations can suffer from poor performance. Consequently, Matlab lets you extend its functionality by calling externally compiled executables through an external interface API. In this article, I show how to create compiled C++ Matlab external interface routines — called "MEX-files" — using this API, and compare the performance of the Matlab C++ external interface routines to functionally equivalent Matlab routines. To do so, I use MEX-files to enhance digital images.
