MATLAB: Bitorreduce is undefined.

MATLAB

I am using MATLAB R2016a. I have to perform or operation on a bit sequence and i need a single bit as a result. For my purpose, "bitorreduce" is the most suitable one command. Problem is, When i convert decimal number to binary and use that number as an argument of this command, MATLAB gives an error saying, "Undefined function or variable 'bitorreduce'. " I am unable to track where the problem is. Please tell me what to do with this error. Any help is much appreciated.

bitorreduce is a part of Fixed Point Designer - if you have a valid license for it, install Fixed Point Designer. Otherwise you have to purchase it to use this function.

There is an oddity in the licensing for those functions.

You need the Fixed-Point Designer license in order to generate code that uses those functions, and generating code is done if you use Rapid Accelerator Mode (and possibly one of the other modes) or if you deploy the code.

However, I see hints from previous questions that for at least one of the modes of use of the functions, the functions can be used in interpreted mode, because some of the modes look like they are built in. So if you were to run the model unoptimized you might possibly not need the license.
