基于simuink的LCL型有源电力滤波器的设计仿真(A LCL type APF simulation that is based on simulink)

里面包含了雷克子波源程序，生成单道地震记录，双同相轴记录，以及tfpt滤波等，对地震记录滤波很有帮助，看看吧(Which contains the Ricker wave source to generate single-channel seismic record, recording double-phase axis, and tfpt filtering, filtering on seismic records is helpful to see it)

改进平方根法求解对称正定线性方程组，用matlab编写，可以在一定程度上提高求解效率。其中MRoot_squaring.m为原做法，sparse_cmp.m为二维等带宽存储，Moot_zonal.m为二维等带宽存储的平方根法求解(To improve the square root method to solve symmetric positive definite system of linear equations using matlab to prepare, to a certain extent improve the efficiency of solving. MRoot_squaring.m which the original approach, sparse_cmp.m for the two-dimensional, such as memory bandwidth, Moot_zonal.m for the two-dimensional, such as the square root of bandwidth storage method)

this code is mainly used in filter design.
