Foreach for containers.Map 1.0

Matlab offers functionality for maps / dictionaries (a key-value store datatype). Iterating over a map can be cumbersome and that's where foreach steps in.Usingresultmap = foreach(map, fctH)calls function handle fctH with each item of the map. The result is stored in the resultmap which has the same keys as the original map.If you have two or more datasets, and you want to process/plot them identically one function call is enough.This turned out to be useful if you write a script processing one dataset. But then you want to compare to another ... either you can duplicate code or you iterate over the items. Foreach simplifies this iteration and keeps a readable key to the dataset ('which dataset has index 3?')So long it's not much more than iterating over a cell array. However, if you combine foreach with some anonymous functions you get a much more powerful tool: foreach can call the function handle with the current iteration key so that one f.ex. can attach the corresponding legend-entry to a plot, using the corresponding axis ...Try also 'help foreach' for more information and examples.I hope you'll find it useful. Feedback is welcome!
