Error: Cell contents reference from a non-cell array object - matlab

Question

when I run the code below, I got the following error :
Cell contents reference from a non-cell array object.
folder can take 1 or several folders
for x=1:numel(folder)
y{x} = fullfile(folder{x},'Status.xml');
getFile = fileread(char(y{x}));
content{x} = strtok(getFile ,';');
end
>>whos folder
Name Size Bytes Class Attributes
folder 1x1 941 struct
>> numel(folder)
ans=
1

Answer 1

Assuming folder is a cell array, I believe this should work:
y = cell(numel(folder), 1);
for x=1:numel(folder)
y{x} = fullfile(folder{x},'Status');
getFile = fileread(char(y{x}));
content{x} = strtok(getFile ,';');
end
Your error is most likely with y{ii}. I guess y is not pre-defined.
Also: you use ii as index in y, whereas you use x in the loop.
In case folder is a normal matrix, have you tried using just folder(x)?
UPDATE:
I see from your updated question that folder is a struct, not a cell. Try the following, where you substitute .field with whatever you name your entries in folder.
y = cell(numel(folder), 1);
content = cell(numel(folder), 1);
for x=1:numel(folder)
y{x} = fullfile(folder(x).field,'Status');
getFile = fileread(char(y{x}));
content{x} = strtok(getFile ,';');
end
