Considering the existing teaching situation and features of the course of circuit analysis, computer simulation technologies have already been introduced into teaching progress, such as Multisim software, it is a popular software which has alrkeady been applied in circuit analysis, and the MATLAB software, in traditional sense, it has always been used in communication field.But with the development of software, a novel application of MATLAB has been put forward.By its component-level circuit simulation, MATLAB can do the circuit analysis, and its simulation result is same as Multisims simulation result.Then, in addition to Multisim, we supply a new method of MATLABto help students to understand the abstract theory better and simulate their learning positivity in the course of circuit analysis, thereby, optimizing the effect of teaching.
