I have a 2 column matrix with some data. The fist column represents a time index, and the second column represents data for that time index:
whatIhave.png
so I want to create a matrix that looks like the one below:
whatIwant.png
so that I can plot a scatter that looks the one below:
plotwhatIwant.png
I have tried findgroups without success. How best can I implement that?
Thanks a lot for your assistance.

time_data=[1 1 1 2 3 3 3 4 4];
data=[10 16 14 18 13 14 23 26 29];
time_data1=unique(time_data);
data_result=cell(1,length(time_data1));
for i=1:length(time_data1)
idx=find(time_data==time_data1(i));
data_result{i}=data(idx);
end
data_result
The resultant groups are saved in a cell array.
Results:
data_result =
1×4 cell array
[1×3 double] [18] [1×3 double] [1×2 double]
>> data_result{1}
ans =
10 16 14
>> data_result{2}
ans =
18
>> data_result{3}
ans =
13 14 23
>> data_result{4}
ans =
26 29
