Problem 42618. Is this function available?

Created by Matthew Eicholtz

Solve Later

Sometimes it is difficult to remember which functions are not allowed on the Cody platform. Given a function as a string, return true if it is available on Cody and false otherwise.

The test suite will be updated periodically, so hard-coding the answers will eventually fail.

Examples

isavailable('bsxfun') returns true

isavailable('pdist2') returns false

You mix two things: functions not allowed on Cody for safety reasons (evalin, assignin...) and toolbox functions not available (imfindcircles, ocr ...).
I am curious to know how you can make the difference. :.)

I realize there is a mix. That is part of the reason I created the problem.

Jean-Marie Sainthillier on 21 Sep 2015

Yes, but if you update the test suite with other Cody restricted functions (str2func, evalc) ?

With this mix a player can't submit a permanent solution. It's bothers me.

But maybe I am boring...
Interesting problem anyway.

Point well taken. I will not update the test suite until I verify that a permanent solution exists.

Maybe you should evaluate the existance of functions dinamically using try and catch as I did. The only problem is that functions such as eval or feval are available at cody although your test suite declares that they aren't. The system just doesn't allow us to use some functions, but they are there. So are they available or not? I would say that they are*.

* There are even ways to bypass this restriction.
