Abstract:

Much matrix calculation is usually needed in circuit calculation.Now computers have been widely used to assist circuit analysis and design.Using Matlab's powerful computation function and GUI interface development,the platform adopts a universal list method and achieves the function of automatic steady-state circuit calculation.Users don't need programming.They only need to input relevant information of a circuit and the platform can directly calculate each node voltage,branch voltage and branch current,and draw the various wave figures for users.The Platform provides an effective aid for steady-state circuit analysis,and it can be used in the teaching of analog circuits.

Key words: steady-state circuit,Matlab,list,automatic solving
