Does MATLAB java.util have non-hash map/set? -

-

java.util.map/set abstract. have java.util.hashmap/hashset/hashtable. have map/set sorted keys in java.util?

sure, treeset, treemap.

documentation part of java. e.g., can start here: https://docs.oracle.com/javase/7/docs/api/java/util/treeset.html

some examples:

>> x = java.util.treeset; >> x.add(2); >> x.add(1); >> x.add(3); >> x x = [1.0, 2.0, 3.0]  >> y = java.util.treemap; >> y.put(10, 'ten'); >> y.put(20, 'twenty'); >> y.put(1, 'one'); >> y y = {1.0=one, 10.0=ten, 20.0=twenty}

to see list of available java classes, it's easiest use javadocs web site, https://docs.oracle.com/javase/7/docs/api/

as noted in comments, calling java classes matlab not particularly fast. believe matlab uses java reflection construct allow execution of ad hoc, uncompiled java code ... not fast. still useful.
