我正在尝试从文本文件中读取数据并在 Matlab 中对其进行 3D 绘图。目前,我得到的只是一个空白图,所以我的猜测是数据没有正确存储或根本没有存储。另外,我不希望每个向量末尾都有 1.000000,所以我怎么能忽略它呢?谢谢。
这是文件:

这是代码:
file = fopen('C:\Program Files (x86)\Notepad++\testFile.txt'); % open text file
tline = fgetl(file); % read line by line and remove new line characters
% declare empty arrays
CX = [];
CY = [];
CZ = [];
while ischar(tline) % true if tline is a character array
temp = textscan(tline,'%n%n%n', 'delimiter',',');
% convert all the cell fields to a matrix
CX = vertcat(CX, cell2mat(temp));
CY = vertcat(CY, cell2mat(temp));
CZ = vertcat(CZ, cell2mat(temp));
tline = fgetl(file);
end
fclose(file); % close the file
plot3(CX, CY, CZ) % plot the data and label the axises
xlabel('x')
ylabel('y')
zlabel('z')
