1、問(wèn)題一：?jiǎn)栴}一：球度誤差的網(wǎng)格搜索算法球度誤差的網(wǎng)格搜索算法復(fù)原代碼如下：復(fù)原代碼如下：clearM=load(1.txt)P=[0.00473040.00170270.0018167]f=0.021n=41l=1zuobiao=zeros(700003)%創(chuàng)建mn全零矩陣fi=1:nx(i)=P(1)f2f(i1)nfj=1:ny(j)=P(2)f2f(j1)nfk=1:nz(k)=P(3)f2f(k1)nfc=1:36R(c)=sq

2、rt((M(c1)x(i))^2(M(c2)y(j))^2(M(c3)z(k))^2)endRmax(l)=max(R[]2)Rmin(l)=min(R[]2)W(l)=Rmax(l)Rmin(l)zuobiao(l:)=[x(i)y(j)z(k)]l=l1endendendw=st(W2)%最大內(nèi)接球法Rout=min(Rmax[]2)Oout=zuobiao(find(Rmax==Rout):)rout=Rmin(find(Rmax
