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)
