Another algorithm to determine if it is a state transfer matrix

This paper introduces another method that can be used to determine whether it is a state transfer matrix, the traditional method is to calculate the product of several matrices, but usually this product will have the operation of the exponential function, especially if it involves the operation of complex numbers will be more troublesome, the innovation of this paper is to convert the operation of the exponential function to the operation of the number, for the convenience of the calculation, the next step will be used to determine whether it is a matrix function.
