I would like to extract values from a structure. I know how to do it in two lines of code, but is it possible in one?
temp = urlAuthsMap.values;
temp{1}
My solution would have been something like [urlAuthsMap.values]{1} but that doesn't work.
>> temp = urlAuthsMap.values
Columns 1 through 11
{1x4 cell} {1x1 cell} {1x3 cell} ...
>> temp{1}
ans =
'S. A. Abraham' 'H. A. Bodner' 'C. G. Harrington' 'R. C. White Jr.'

V = values(urlAuthsMap,KH); % KH is the key you want. See key.
From the link you showed above .... ;-)

Thanks a lot for your answer by email. i'll paste it in below
As far as I know, there is no way to index into newMap the way you want to.
keySet = {'Jun','Jul','Aug'}; valueSet = [ 69.9, 32.3, 37.3]; newMap = containers.Map(keySet,valueSet); values(newMap,keySet(1)) % This is how to do it.
As far as your other example, try this:
a{1} = [1,2,3] a{2}=[4,5,6]
a{2}(1)

urlAuthsMap.values = {'S. A. Abraham', 'H. A. Bodner', 'C. G. Harrington', 'R. C. White Jr.'}
% Here's how to do it.
caName1 = urlAuthsMap.values(1) % This is a cell.
strName1 = urlAuthsMap.values{1} % This is a string.

Thanks, I've tried this but am getting errors for both. I realized that maybe my map object is special and doesn't work like a normal cell array. Any ideas?
urlAuthsMap.values{1} Error using containers.Map/values Invalid input for argument 2 (rhs2): Value must be 'cell'.
>> urlAuthsMap.values(1) Error using containers.Map/values Invalid input for argument 2 (rhs2): Value must be 'cell'.
