I have the above mentioned issue when I try to run this code:
keys = [DS.UserNum];
valueSet = [DS.CarNum];
M = containers.Map(keys,valueSet)
UserNum Car Num
1 [123,257,345,235,553]
2 834
3 [111,156]
4 [111,445,642,164]
5 []
--> The number of keys and values must be the same. How can I correct that.

Thank ! that was it. But this is weird as on the mathwork website you got the following format
keySet = {'Jan','Feb','Mar','Apr'};
valueSet = [327.2 368.2 197.6 178.4];
M = containers.Map(keySet,valueSet)
keySet is put between {} and valueSet between []

In that example, the keys are character vectors, and the values are scalar numeric. Character vectors are collections of characters.
In your code, the keys are scalar numeric, and the values are vectors of numeric — collections of numbers.
In both cases, collections use {} and scalars use []
