这些是 sismic 数据，我想读取这些数据并保存在不同的变量 X、Y、Z 中。Chanel 1=x Chanel 2=y Chanel 3=z 然后我想绘制它。

我会通过一次读取一行文件来执行此操作，检查该行是否是块标记，如果不使用 textscan 来解析该行中的双精度数。

fid = fopen('c:\temp\temp.txt');
vars = {'X','Y','Z'};
varIndex = 0;
current = [];
while 1
    tline = fgetl(fid);
    if ~ischar(tline), break, end

    newVar = ~isempty(strfind(tline,'Chan'));

    if newVar
        if varIndex > 0
            eval([ vars{varIndex} '=current;']);
            current = [];
        end
        varIndex = varIndex + 1;
    else
        newData = textscan(tline,'%f');
        current = [current newData{:}'];
    end    
    disp(tline)
end

eval([ vars{varIndex} '=current;']);
current = [];

fclose(fid)
