Dear all, According to the following code:
i=load('138078.mat')
i =
imageLabelCell: {1x6 cell}
subjectIDList: [1105 1107 1108 1112 1116 1124]
>> i.imageLabelCell
ans =
Columns 1 through 5
[481x321 double] [481x321 double] [481x321 double] [481x321 double] [481x321 double]
Column 6
[481x321 double]
I want to extract the 1st column of i.imageLabelCell which is a matrix 481x321 , Could anyone help me please ?

Try
i.imageLabelCell{1}(:,1)

You write extract the 1st column of i.imageLabelCell which is a matrix 481x321 and it is i.imageLabelCell{1}(:,:) I'm missing something.
i.imageLabelCell has six cells each with one matrix. Thus there are altogether six 1st column. Maybe, you are looking for
cell2mat( cellfun( @(c) c(:,1), i.imageLabelCell, 'uni',false ) )
Matlab (R2016a) isn't smart enough to understand
>> [i.imageLabelCell{:}(:,1)]
Expected one output from a curly brace or dot indexing expression, but there were 3 results.
