Find Unique values in array
显示 更早的评论
Hi all,
I am trying to create a new array contains ONLY the unique values (same values but not repeated) which in the following case are 90 0 45
I used unique function, however, the function also returns the same data as in x, but in sorted order. I DO NOT want them in sorted order,
Also, I would like to obtain the index of the unique values in the x
like index=[1,2,9]
clear all;
clc;
x=[90 0 0 90 90 90 90 90 45 0 0 0];
y=unique(x)

clc;
x=[90 0 0 90 90 90 90 90 45 0 0 0];
[y, idx] = unique(x, 'stable')
output
y =
90 0 45
idx =
1
2

Correct syntax is i=1:4 (use colon)
for i=1:4
z(:,:,i)=A(:,:,i)
end

Try try something like this
idx = [1 4];
for i=1:numel(idx)
z(:,:,i)=A(:,:,idx(i))
end
