[MATLAB图像处理] 求助：Matlab读取Gambit网格数据后，怎么画出图像

[fusijie1]

rt，小弟询问Matlab读取了Gambit网格数据后，怎么能显示出图像呢？不胜感激！，附读取程序：
function [Nv, VX, VY, VZ, K, EToV] = MeshReaderGambit3D(FileName)

% function [Nv, VX, VY, VZ, K, EToV] = MeshReaderGambit3D(FileName)
% Purpose : Read in basic grid information to build grid
% NOTE : gambit *.neu format is assumed

Fid = fopen(FileName, 'rt');

% read intro
for i=1:6
line = fgetl(Fid);
end

% fine number of nodes and number of elements
dims = fscanf(Fid, '%d');

Nv = dims(1); K = dims(2);

for i=1:2
line = fgetl(Fid);
end

% read node coordinates
xyz = fscanf(Fid, '%lf', [4, Nv]);
xyz = xyz(2:4, ;
VX = xyz(1,; VY = xyz(2,; VZ = xyz(3,;

for i=1:3
line = fgetl(Fid);
end

% read element to node connectivity
EToV = zeros(K, 4);
for k = 1:K
line = fgetl(Fid);
tmpcon = sscanf(line, '%lf');
EToV(k,1:4) = tmpcon(4:7);
end
return
