Hi,
I have a nested struct user.data (attached) anda I want to find the unique values of the field touristicRoute (user.data.touristicRoute)
I have tried this code:
for m=1:size(Cluster_USERS,1)
for i=1:size(userTouristicTraj(m).touristicData,2)
if (user(m).data(i).touristicRoute~=0)
uniqueValues=unique(user(m).data(i).touristicRoute)
end
end
end
but it doesn't give me the right value, can you help me?

What is "the right value"? The posted code does give you "unique values of the field touristicRoute". Or do you get an error message? Please explain exactly, what you need.

load matlab.mat
N = length(user) ;
iwant = cell(N,1) ;
for i = 1:N
M = length(user(i).data) ;
val = cell(M,1) ;
for j = 1:M
val{j} = user(i).data(j).touristicRoute ;
end
val = cell2mat(val) ;
iwant{i} = unique(val) ;
end
