我想从下面的文本文件中提取灰色区域的数据，我想使用 matlab。无法计算标题中的行数，因为每次生成文本文件时都会发生变化。
它应该是这样的：
%open the file
fin = fopen('panair.out');
buffer = fgetl(fin)
if buffer(2:17)=='totals for column'
j=1
for i=1:3
tmp=fgetl(fin)
end
buffer=fgetl(fin);
temp = strread(38:44);
wingsection.area(j,k)= strread(temp, '%7.4f');
temp = strread(38:44);
wingsection.fx(j,k)= strread(temp, '%7.4f');
temp = strread(38:44);
wingsection.fy(j,k)= strread(temp, '%7.4f');
temp = strread(38:44);
wingsection.fz(j,k)= strread(temp, '%7.4f');
temp = strread(38:44);
wingsection.mx(j,k)= strread(temp, '%7.4f');
temp = strread(38:44);
wingsection.my(j,k)= strread(temp, '%7.4f');
temp = strread(38:44);
wingsection.mz(j,k)= strread(temp, '%7.4f');
j=j+1;
else
end
%close file
fclose(fin);
或者也许 textscan 更快？
