摘要
基于信号重构的思想，提出了一种系统分析方法．该方法是对时域矩阵方法的改进，既保留了时域矩阵方法快速性的特点，又能在不改变仿真步长的前提下，提高仿真精度．对该方法的截断误差做出了估计，并证明了该方法的收敛性．仿真例子说明了其有效性．
Based on signal reconstruction, a system analysis method is proposed. The method is an extention of time-domain matrix simulation approach. It remains the characteristic of fastness of time-domain matrix method, and has higher simulation precision without changing simulation step. The truncation error of the method is estimated and its convergence is proved. An example is given to demonstrate the availability of the proposed method.
