在Matlab上的二进制数据 [英] Working on Binary Data in Matlab

问题描述

我已加载在MATLAB中的文本文件测试文件。负载的功能现在已经创建了一个变量测试与值

I have loaded a text file test file in matlab. The load function has now created a variable test with values

1 2  3  4   5
2 3 NaN NaN NaN

现在我有一个初始化的变量 X = [0 0 0 0 0 0 0 0 0 0 0] 和 Y = [0 0 0 0 0 0 0 0 0 0 0] 。
我想 X 读测试变量的第一个行和与之对应的读取改变其元素的值数从 0 到 1 。假设它读 1 ，就应该改变其元素 X（1）从 0 到 1 。同样是应该做同样的WRT第二行测试。

Now I have a initialized variable X = [0 0 0 0 0 0 0 0 0 0 0] and Y = [0 0 0 0 0 0 0 0 0 0 0]. I want X to read the first row of test variable and corresponding to the number it reads change its value of the element from 0 to 1. Suppose it reads 1, it should change its element X(1) from 0 to 1. Similarly Y should do the same wrt second row of test.

任何想法，我应该怎么进行呢？

Any idea how should I proceed?

推荐答案

您可以索引直接进入像这样一个向量：

You can index directly into a vector like so:

x=zeros(1,10);%# your zero vector
a=[1,3,7,8];  %# the index of sports you like
x(a)=1        %# change from 0 to 1

x =

     1     0     1     0     0     0     1     1     0     0

这是您的评论去，我觉得这是你想要的。

Going by your comment, I think this is what you want.
