Question

求助 我有三组数据 请问 如何用matlab把它画成三维曲面图 数据如下：

x=[256.712546009868,181.649359684609,120.945711734739,242.058563037584,263.957329481755,208.602141242474,195.940615916242,146.038931643278,200.596836019928,185.362981214263,69.3979887230404,146.509078271195,216.210601329597,84.0244751937118,210.018742190754,236.688320635148,279.720773128167,75.7734974196698,220.754014365644,126.577732890067,180.179993757904,375.541115636297,237.074053230004,228.631120472936,183.535492973315,222.550485307298,276.226972327541];

Answer 1

你的z是一维的，只能画出三维曲线图来
plot3(x,y,z)
画曲面要求z必须是二维的数据
