ROI

是一个完成循环卷积的MATLAB程序 实现方法实在时域完成的，不同于简单的频域实现，有较好的注释，一看就能懂，用的是矩阵的方法实现的(Is a cyclic convolution achieve implementation of the MATLAB program with it, the finish time domain, frequency domain is different from the simple implementation, there is a good note, one can look to understand, are used in the implementation matrix)

用途：三阶样条插值（一阶导数边界条件） 格式：m=maspline(x,y,dy0,dyn,xx), x为节点向量，y为数据， dy0,dyn为左右两端点的一阶导数如果xx缺省，则输出各节点的 的一阶导数值，，m为xx的三阶样条插值(Uses: third-order spline interpolation (first order derivative boundary condition) format: m = maspline (x, y, dy0, dyn, xx), x is the node vector, y for the data, dy0, dyn left and right ends of points a derivative, if xx default, then the output of each node of the of a first derivative values,, m for the third-order spline interpolation xx)

说明：  一组逆变器电路的Matlab仿真源程序，包括单相、三相、多电平等多种逆变电路，初学者可以看看(A Matlab simulation of the inverter circuit source, including single-phase, three-phase, multi-level equal to a variety of inverter circuit, beginners can take a look)
