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.
