i having difficulty in understanding significance of classloader in resourcebundle.getbundle(bundlename, locale, classloader) api . what practical scenario want provide custom loader api? a java application might have multiple class loaders. example, j2ee application running on tomcat or glassfish has multiple tiers of classloaders - belonging j2ee server itself, being made webapp (otherwise webapp able access classes belonging other webapps) , custom classloaders might have instantiated yourself. standalone java apps might have multiple classloaders. example, if application supports plugins , each of these plugins contained in own jar file (local or remote) in order load plugin's classes @ runtime have create own classloaders so. therefore, when load resourcebundle have select appropriate classloader ensure resource loaded correct source. here's simple example... imagine application contains /version.properties file , jvm has similar, yet different, /vers...

i have matlab function f(w) returns (n x n) square matrix. have vector ws = [w_1, w_2, ... w_m] contains m parameters w_i . create 3d array contains m "planes" f(w_i) . possible in matlab using arrayfun() et al. create 3d array without using for loops iterate on parameter vector ws , concatenating results? if want see how few functions can used, here's approach arrayfun , cell2mat , reshape combined (i changed last line according daniel's comment): f = @(w) [w 2*w; 3*w 4*w]; %// random function returns array of fixed size w = 1:4; %// random input function out = cell2mat(reshape(arrayfun(@(x) f(w(x)), w, 'uniformoutput', 0),1,1,[])); you (probably fastest of these approaches, there faster approaches): out = f(reshape(w,1,1,[])) or use loop (notice order of loop): for ii = numel(w):-1:1 out(:,:,ii) = f(w(ii)); %// no pre-allocation necessary end or more traditional loop approach: out = zeros(2,2,4); %// pre-alloca...
