Hello all, I would like to rearrange the matrix according to the values in the first column. the first column represents station number and the second column represents value acquired from the corresponding station ( I attached the file). I have 9 stations, so I want a n x 9 matrix where n is the values from each station. It would be like
0 0 0 0
10 10 10 10
20 20 20 20
30 30 30 30
50 50 50 50
75 75 75 75
125 125
150 150

load(websave('question.mat','https://www.mathworks.com/matlabcentral/answers/uploaded_files/464105/question.mat'));
G=findgroups(stationdepth(:,1));
n=max(histcounts(G,1:max(G)+1));
out=nan(n,9);
for i=1:9
bool=(G==i);
out(1:nnz(bool),i)=stationdepth(bool,2);
end
out
