Comparing elements within a cell array
이전 댓글 표시
Hi everyone, I have two cell arrays x and y. I want compare values of x based on y. Like x{1,1} in y contains [2,4]. So it will compare 1st element of x which is [4,7,8] with 2nd and 4th element of x and get the common values. then 2nd element of x is compared with 1st and 4th element of x because 2nd element of x is [1,4] and so on.
x= {[4,7,8];[1,5,6];[1,7,8],[1,4]}
y= {[2,4];[1,4];[1,2,4],3}
Result will look like this:
result{1,1} = {0;[7,8]} %comparison of x{1,1} with x{2,1} and x{4,1}
result{2,1}= {0;1} %comparison of x{2,1} with x{1,1} and x{4,1}
result{3,1}= {[7,8];1;1} %comparison of x{3,1} with x{1,1}, x{2,1} and x{4,1}
result{4,1}={1} %comparison of x{4,1} with x{3,1}
Zero is placed where there is no common values found.
Thanks in advance.

@lucksBi: Zero is not a "common value" to any of those arrays, so where does the zero come from? Why not just use an empty array?
In any case, this would be quite easy to achieve using loops and intersect, so I am sure that you must have written something. Please show us what you have tried so far.

I doubt there is a direct method of doing this. You could try to parallelize this by using parfor or cellfun.
