Abstract
In this article, a new algorithm that takes the truth vector of a 5-valued function as its input and proceeds to generate all of the function's fixed polarity Reed-Muller (FPRM) spectral coefficient vectors one by one in a certain sequence is presented. The experimental results for this algorithm are compared with other methods and it was found that it is more efficient than other methods for some functions. Moreover, the presented algorithm requires very low memory storage.
