intbnddistances.m

本代码为基于matlab的求解偏微分方程的利用径向基函数的无网格方法的源码

function distances = intbnddistances (intpoints, bndpoints)  
% create distance matrix from int and bnd point matrices
[numbndpoints,dim]=size(bndpoints);                  % get dimensions
[numintpoints,dim]=size(intpoints);
bndsquares=points2normsquares(bndpoints);
intsquares=points2normsquares(intpoints);
distances=sqrt(repmat(intsquares,1,numbndpoints)+repmat(bndsquares,1,numintpoints)'...
        -2*intpoints*bndpoints');
