Thread Subject: how to construct empty containers.Map with integer KeyType

Howdy,

this is real simple but I can't figure it out. How do I construct an empty
containers.Map with integer KeyType. The default is char, and Matlab autodetects
numeric types if they are given as keys, but I want to start with an empty map.

thanks,
Danny

Hi Danny,

Currently, at the time of writing this reply, there is no way to do this. The workaround is to construct with dummy variables of the right type, and them remove the dummy entries.

Is it helpful to preallocate a containers.Map array ? If so, how do you preallocate it? Thanks Matt
