how use mesh() draw gaussians in 2d, inside matlab function...

function  g(mean,cov,c)  icov = inv(cov); det_cov = det(cov); const = 1/(2*pi*sqrt(det_cov));  xx = linspace(mean(1)-3*sqrt(cov(1,1)),mean(1)+3*sqrt(cov(1,1))); yy = linspace(mean(2)-3*sqrt(cov(2,2)),mean(2)+3*sqrt(cov(2,2)));  [x y] = meshgrid(xx,yy); mx=x-mean(1); = y-mean(2);  z=const*exp(-0.5*(icov(1,1)*mx.^2+icov(2,1)*mx.*my +icov(2,1)*my.*mx+icov(2,2)*my.^2)); contour(x,y,z,c);

simply replace contour mesh.

also, try not use mean , cov variable names. mean , cov matlab functions, , while spelling different, you're still setting hard-to-find bugs.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
