Hello I have a function that returns a containers.Map object with values as 1xn cell arrays. For example
map=containers.Map({'OBJECT', 'COLOR', 'WGT'},{{'obj1','obj2','obj3'},{'red','blue','green'},{1.2,2.54,8.12}});
The values in map are 3 1x3 cells.
>> map.values
ans =
{1x3 cell} {1x3 cell} {1x3 cell}
I would like to join the 3 1x3 cell data into 3x3 cell data like this
>> transpose([{'obj1','obj2','obj3'};{'red','blue','green'};{1.2,2.54,8.12}])
ans =
'obj1' 'red' [1.2000]
'obj2' 'blue' [2.5400]
'obj3' 'green' [8.1200]
How do I do this?
Thanks Bhaskar

One possibility:
v = map.values;
vc = [v{1}', v{2}', v{3}']
vc =
'red' 'obj1' [1.2000e+000]
'blue' 'obj2' [2.5400e+000]
'green' 'obj3' [8.1200e+000]

How do I make this dynamic. The size is not always 3. Can vc be made by a loop or some other construct?

This works:
vc = [];
for k1 = 1:size(v,2)
vc = [vc, v{k1}'];
end
That assumes they’re all the same length.

I was able to do this using your idea.
vc=cell(3,3);
keys=map.keys;
for i=1:3
vc(:,i)=map(keys{i});
end
Thank you
