db23d.m

用来实现三维阻抗及光学断层成像重建的matlab程序

function [dd] = db23d(x1,y1,z1,x2,y2,z2);
%function [dd] = db23d(x1,y1,z1,x2,y2,z2);
%
%Auxiliary function that caclulates the distance between two points in 3D
%
%
%
%(x1,y1,z1) = The coordinates of the first point in 3D
%(x2,y2,z2) = The coordinates of the second point in 3D
%dd         = Their distance

dd = sqrt((x2 - x1).^2 + (y2 - y1).^2 + (z2 - z1).^2);
