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.

i new combination , permutation related algorithms. have thoughts on how program solve classical problem? there 3 boxes(a,b,c) , 10 balls(1,2,3,...,10), want put balls boxes. result should {box a: ball 1; box b: ball 2,3,4; box c: ball 5 6 7 8 9 10}, {box a: ball 1 2; box b: ball 3 4 5; box c: 7 8 9 10}, .... want combinations (not number of different combinations). furthermore, if there constraint each box contains @ 4 balls? thank you. you can put first ball in of 3 boxes, have 3 variants. there 3 variants second ball, 3 third , on. they independent, have 3^10 variants, , each variant has 1:1 mapping number in range 0..3^10-1. consider number in ternary number system, k-th ternary digit of number tells box (a=0,b=1,c=2) k-th ball belongs to. example 3 balls: number 14 = 112 ternary, first ball in c, second , third in b for case of limited box size simple approach recursive generation - arguments of recursion list of available balls , current combination (li...

i have 4 svg buttons part of main menu on personal webpage. /----------------------------------------------------------------------------------------------------------------------------------/ when 1 clicked, 4 buttons retract corners , respective section revealed (i.e. aboutme button --> aboutme section). originally had svg objects embedded in img tag so: <img class = "button active" id = "person-icon" src = "resources/main-page-icons/person-icon.svg"/> i did because read when there no need animate svg isn't necessary embed in object/embed tag. however, decided today wanted create hover effect svg element. had change img tag object allow styling/animating <object class = "button active" id = "person-icon" data = "resources/main-page-icons/person-icon.svg" type = "image/svg+xml"></object> the hover effect works expected, but can't click it . inspecting element reveals ...
