I'm sure this is probably very easy but I can't seem to crack it. I've got an array like so:
how to find the count of unique values of a column in a array? eg. am having values like 5,10,15,20,25,30,35,40,45,50,55,60 which are repeated in one column of a array. i need count of each elements in that column.댓글 수: 0 댓글을 달려면 ...
Open in MATLAB Online I hope that the below lines of MATLAB code would help in arriving at the above requested solution. ThemeCopy % As per the above description, assuming unique values in arrays “a” and “b” a = [3 1 2 6 4 5]; b = [2 3 1 5 6 4]; % "c" is ...
输入的采样点x = [1, 2, 3, 3, 4];y = [10, 20, 30, 40, 50];% 去除重复的采样点[unique_x, idx] = unique(x);unique_y = y(idx);% 进行插值interp_values = interp1(unique_x, unique_y, 2.5);在上述代码中，unique函数用于去除重复的采样点，并返回唯一的采样点unique_x...

u = unique(B); % The unique values c = histcounts(x, [u, Inf]); The calculation of B is slower then with RunLength.mex, but if runtime is not the problem in your case, you can save the time and effort for compiling. 3 件のコメント 1 件の古いコメン...

In this example, the values 5, 11 and 18 are missing. The vector I am working with is a lot longer and has the values missing in random places. What I want to do is create an array out of A that starts a new column every time there's a gap: ThemeCopy CELL = {[1;...
