defining a map with value as array

how can I define a map, so the key is uint32 and the value is array of int32?

there is an option to define that valueSet but keySet has to be also defined with it.

I need a single key to array of integers. I will be happy for example.

thanks in advanced.

EDIT value as struct is ok also

You can specify the KeyType when creating your map but if you have values of different sizes you have to keep ValueType as any. For example:

mapObj = containers.Map('KeyType','uint32','ValueType','any')
mapObj(2) = int32([1 2 3 4])
>> mapObj(2)

ans =

       1           2           3           4

Obviously the downside is that you can specify some key to take a value of a different type too. Like:

mapObj(3) = 'name'

But I can't imagine this being any real issue in your program. Also a ValueType of struct is not supported yet so you are better off keeping your values as arrays.
