matlab - Find median value of the largest clump of similar values in an array in the most computationally efficient manner -

-
sorry long title, sums up. i looking find median value of largest clump of similar values in array in computationally efficient manner. for example: h = [99,100,101,102,103,180,181,182,5,250,17] i looking 101. the array not sorted, typed in above order easier understanding. array of constant length , can assume there @ least 1 clump of similar values. what have been doing far computing standard deviation 1 of values removed , finding value corresponds largest reduction in std , repeating number of elements in array, terribly inefficient. for j = 1:7 g = double(h); = 1:7 g(i) = nan; t(i) = nanstd(g); end best = find(t==min(t)); h(best) = nan; end x = find(h==max(h)); any thoughts? this possibility bins data , looks bin elements. if distribution consists of separated clusters should work reasonably well. h = [99,100,101,102,103,180,181,182,5,250,17]; nbins = length(h); % <-- set # of bins here [v bins]=

Confusion About C++ Global Namespace -

-
from understanding, appending :: front of namespace refers global namespace, regardless of using statements or parent namespaces. if case, , haven't mis-understood anything, why such code compile (at least in visual studio): namespace foo { namespace bar { class x; } } using namespace foo; int main(void) { ::bar::x x; } using namespace foo; brings contents of namespace foo context of current namespace. since namespace bar among contents of namespace foo , current namespace on line using statement global namespace, namespace bar brought context of global namespace.

java - Object wont move based on angle given? -

so i've been trying make object move based on 2 speeds creates using atan(). every test results in same movement of going straight up. so decided take out , replace inputted angles oddly work the 4 angles 90 180 270 0. i'm not sure why goes directions here's code: public void update() { updatedir(); move(); } public void updatedir(){ dir = math.atan(spdy/spdx); dir =20; //i know here used test if change dir = dir * math.pi / 180.0; system.out.println("dir: " + dir); } public void move() { x += (spd*math.cos(dir)); y -= (spd * math.sin(dir)); } any reason why goes in 4 directions? what @nishant shreshth says true. super important use floating points (like float or double ) instead of int dir , x , y variable. otherwise decimal part dir value might truncated, pretty of problem when use radians , trigonometric functions. also note want use math.atan2(spdy, spdx) instead of default atan method use.

java - JFrame listening for KeyEvent while Iconified -

-
how can keep jframe listening keyevent while state iconified? for example after pressing f1 start program (an auto clicker) , iconify frame (remember because of click focus on frame lost!) :) if you're trying create key-logger program java, don't. it's not tool creating since design isolated os, in other words it's "os-agnostic". need use different tool allegedly nefarious plans such c or c++ since these languages allow closer "metal".

java - found raw type: JComboBox -

-
i have simple source file guiapp1.java trying compile cmd javac. gives me warning : c:\users\thakkar\java>javac guiapp1.java note: guiapp1.java uses unchecked or unsafe operations. note: recompile -xlint:unchecked details. so used cmd javac -xlint guiapp1.java compile source file. it gave me 6 warnings e.g. guiapp1.java:48: warning: [rawtypes] found raw type: jcombobox jcombobox fruits = new jcombobox(fruitoptions); ^ missing type arguments generic class jcombobox<e> e type-variable: e extends object declared in class jcombobox how can solve this? starting java 7 many swing components use generics, older code produce warning raw types. for combobox example can eliminate warning if provide type of objects holds e.g. should use jcombobox<string> fruits = new jcombobox<>(fruitoptions); if fruitoptions string[] . if use other type change accordingly.
