可以帮我看看吗？上传的文件是在网上下的一个公开的数据集，如何用fread来读取，如何在matlab中生成之前所说的矩阵呢？谢谢啊！...

matrix_index = {{9,69,169,186,261,317,327,768,989,994,1088}
{21,137,291,675,712,1088}
{3,12,13,251,420,425,513,602,757,793,820,848,872,873,951,956}
{8,483,618,730,741,958,1031,1036,1062,1088}
{12,226,327,421,569,836,1082}
{17,21,84,286,292,511,646,813,839,989,1028,1036,1088}
{21,102,122,146,452,515,623,951,1088}
{3,19,83,407,457,543,585,800,890,1046,1088}
{13,219,221,376,379,412,464,662,667,674,690,844,984,1023,1088}
{5,29,81,255,257,258,658,702,923,967,1010,1088}
{17,73,84,102,201,512,558,616,668,669,813,1088}};

matrix_binary = zeros(11,1101);
for i = 1:11
    matrix_binary(i,cell2mat(matrix_index{i})) = 1;
end

谢谢大神，那如果说有三千多行，一千多列的矩阵，怎么办呢？因为这个图我只是截的其中一部分，应该不会要把每行都这样写呀，估计也行不通，还望大神赐教，谢谢！...
