matlab - How to separate rows from a matrix? -

-

i have large matrix of size 16384 x 16. need obtain 512 x 512 matrix it. matrix should joined follows, l matrix of size 16384 x 16.by default l arranged below

    l = [l1          l2          l3          .          .          l32].

i need obtain l such that,g(ie;the new 512x512 matrix)

     g = [l1l2...l32]

here each l 512x16 matrix. tried 32x32 matrix , obtained results correctly not able larger matrix. should do? following code had used

       w1 = 32;        ans1 = l(1:w1,:);        ans2 = l(w1+1:end,:);        g = [ans1,ans2];

thanks.

one approach permute & reshape -

cutlen = 512;  %// "cut" after every cutlen rows g = reshape(permute(reshape(l,cutlen,[],size(l,2)),[1 3 2]),cutlen,[]);

i wish write custom appender on basis of outputstreamappender . wrote following class package tests; import java.io.ioexception; import java.io.outputstream; import ch.qos.logback.core.outputstreamappender; public class myappender<e> extends outputstreamappender<e> { public myappender() { system.out.println("myappender created"); setoutputstream(new outputstream() { @override public void write(int b) throws ioexception { throw new unsupportedoperationexception(); } }); } } then wrote following runner: package tests; import org.slf4j.loggerfactory; import ch.qos.logback.classic.logger; public class runner { private static final logger log = (logger) loggerfactory.getlogger(runner.class); public static void main(string[] args) { //log.addappender(new myappender<iloggingevent>()); log.info("hello world"); } } finall...

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
