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.
