Thread Subject: different data types

I have a column of mixed data in an excel sheet that
appears as the following in Matlab:

PolygonROI =

    'PolygonROI'
    [ -1]
    [ -1]
    '1,3,4'
    '1,3,4'



I am trying to paste in certain cells of 'PolygonROI' into
an empty variable. I tried to create an array:

a=zeros(5,1);

and then put certain values of 'PolygonROI' inside a given
cell:

a(2,1) = PolygonROI(4)

with the hope of outputing:

a=
0
0
0
'1,3,4'
0

However, it didn't output this because it said "Conversion
to double from cell is not possible."

Does anyone have any suggestions?

Thanks!!

Hi
PolygonROI is a cell array (see help on cell)
So you can do :
a=cell(5,1)
a{4}=PolygonROI{4};
