While calculating superlattice transmission coefficient,the wave functions on the two sides of interface of potential well and potential barrier can be extended into a number of linear equations which can be described with a matrix equation.The superlattice transmission coefficient can be obtained with matrix left division command in MATLAB.It is simple in concept,convenient in operation,practical in universality and without more efforts in programming compared with other methods such as iteration and transfer matrix.
