显示 更早的评论
Hi all, I have a dataset abc (6x1)and a cell array xyz(4x1). I want to find the common observations. Dataset abc:
'ObsNames' y 'obs1' 0 'obs2' 0 'obs3' 0 'obs4' 0 'obs5' 0 'obs6' 1
cell array: 4×1 cell array
'obs2'
'obs3'
'obs4'
'obs6'I want to get a dataset that contains only the lines present in xyz array.

Can you upload a .mat file with your variables?

Okay, I've never worked with datasets but they are quite similar to tables.
%%Load data
d1=load('xyz.mat');
d2=load('abc.mat');
%%Extract cell array with xyz names
xyzNames=d1.ObsNames_ds_ACP_selected_vars
%%Extract cell array with abc names and values
abc=d2.ds_ACP_selected_vars
abcNames=abs.Properties.ObsNames
abcValues=abc.Classvar;
%%Compare
[~,b]=intersect(abcNames,xyzNames)
%%Names
abcNames(b)
ans =
4×1 cell array
{'CCImpOpA' }
{'ProdottiAccesiMens'}
{'ProdottiInEssere' }
{'classe_eta' }
%%corresponding values
abcValues(b)
ans =
0
