How to use external DLL in Matlab ?

[Lyric]

That's juste a question from a beginner

In fact, I just want to know how to notify the dll function and how to "summon them" to help me in my job.

Thank's a lot

you have to compile the c-code using the mex-function in matlab. if you compile the file on a windows system, it automatically has the extension .dll .

after that you can use the .dll if it was a regular matlab .m-function. The only difference as far as I know is, that it is not beeing compiled during execution.
