How to use matlab's filter function to compute samples of the impulse response of a filter? -


i have following code far:

[b,a] = ellip(4,.2,40,[.41 .47]); //elliptical filter [h,w] = freqz(b,a,4096);

i need figure out how compute 4096 samples of impulse response of filter. can't figure out how. thanks.

you have b , a, can filter impulse impulse response:

imp = [1, zeros(1, 4095)] h = filter(b, a, imp);

for example, plot(h) should yield this:

java Extracting Zip file -

i'm looking way extract zip file. far have tried java.util.zip , org.apache.commons.compress, both gave corrupted output. basically, input zip file contain 1 single .doc file. java.util.zip: output corrupted. org.apache.commons.compress: output blank file, 2 mb size. so far commercial software winrar work perfectly. there java library make use of this? this method using java.util library: public void extractzipnative(file filezip) { zipinputstream zis; stringbuilder sb; try { zis = new zipinputstream(new fileinputstream(filezip)); zipentry ze = zis.getnextentry(); byte[] buffer = new byte[(int) ze.getsize()]; fileoutputstream fos = new fileoutputstream(this.tempfolderpath+ze.getname()); int len; while ((len=zis.read(buffer))>0) { fos.write(buffer); } fos.flush(); fos.close(); } catch (filenotfoundexception e) { // todo auto-generated catch block ...

C# WinForm - loading screen -

i ask how make loading screen (just picture or something) appears while program being loaded, , disappears when program has finished loading. in fancier versions, have seen process bar (%) displayed. how can have that, , how calculate % show on it? i know there form_load() event, not see form_loaded() event, or % property / attribute anywhere. all need create 1 form splash screen , show before main start showing landing page , close splash once landing page loaded. class splashform { //delegate cross thread call close private delegate void closedelegate(); //the type of form displayed splash screen. private static splashform splashform; static public void showsplashscreen() { // make sure launched once. if (splashform != null) return; thread thread = new thread(new threadstart(splashform.showform)); thread.isbackground = true; thread.setapartmentstate(apartmentstate.sta); thread....
