This is my code but I'm sure MATLAB provides a more elegant way to do this. Any thoughts?
all = csvread('TRAINING_i.csv');
actual = csvread('TRAINING_INPUTS.csv');
indTraining = zeros(size(actual,1),1);
for i = 1:size(actual,1)
indTraining(i,1) = find(ismember(all, actual(i,:), 'rows'));
end
I have following codes. I used it to get some data from another domain address. In my local network. If anyone can tell me What I did mistake here or give me resolves.

我不知道我是否完全按照，但我认为这就是你想要做的：
A = [1 2;
3 4;
5 6;
7 8];
B = [3 4;
7 8];
for i = 1:size(B,1)
indTraining(i,1) = find(ismember(A, B(i,:), 'rows'));
end
indTraining 现在是[2, 4]. 这更容易实现，如下所示：
[~, indTraining] = ismember(B, A, 'rows')
不需要循环，也不需要find. 如果您发现自己find在 Matlab 中使用了一个常用函数，则值得首先检查该函数的文档，因为许多常用函数的第二个或第三个输出通常是该函数所做的索引，并且会为您省去麻烦，例如第二个输出max等_
最后，不要all在 matlab 中用作变量名，因为您掩盖了一个非常有用的函数。
