ABSTRACT = {In this paper, we do research on generating unitary matrices for quantum 
circuits automatically. We consider that quantum circuits are divided into six types, and 
the unitary operator expressions for each type are offered. Based on this, we propose an 
algorithm for computing the circuit unitary matrices in detail. Then, for quantum logic 
circuits composed of quantum logic gates, a faster method to compute unitary matrices of 
quantum circuits with truth table is introduced as a supplement. Finally, we apply the 
proposed algorithm to different reversible benchmark circuits based on NCT library 
(including NOT gate, Controlled-NOT gate, Toffoli gate) and generalized Toffoli (GT) 
library and provide our experimental results.},
