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)

Ritz法解决-u +u=x 0<x<1，u(0)=0,u(1)=0的有限元边值问题。精确解为u(x)=1/(exp(1)-1/exp(1))*exp(-x)+1/(1/exp(1)-exp(1))*exp(x)+x，基函数为g(i)=sin(i*pi*x)(This matlab code is used to solve the boundary value problem of the differential equation: -u +u=x 0<x<1，u(0)=0,u(1)=0, where the accurate solution is : u(x)=1/(exp(1)-1/exp(1))*exp(-x)+1/(1/exp(1)-exp(1))*exp(x)+x)
