Why some functions does not open?

Some Matlab toolbox functions doesn't open, we only get their explanation like some functions:

>> open cummin

>> open cummax

>> open min

...

@Said BOUREZG: who said that they have to open? Where is it written that every function must be able to be opened ?

No compiled function will open in the editor. This is the expected behavior.

[Said BOUREZG]

Thank you for the answer.

The functions cannot be "opened", because they are compiled. Some functions of Matlab's toolboxes are shipped as M-files, some are "built-in". Then only the documentation in the help section is visible for the users.

What is the purpose of "opening" the code of min?

[Said BOUREZG]

Thank you for the answer, and about the purpose, it's just a curiosity.

Matlab's license condition, which have been accepted by all users, forbid a reverse engineering. Therefore digging in the code must be limited. Even if this answer would contain the hint, that digging in the code would be possible at all, might be illegal.

But if you are really curios, try to contact the author. They are scientists also and under certain conditions they are interested in discussions.
