Trapezoidal Numerical Integration in MATLAB without using a FOR loop? -


i'm following numerical methods course , made small matlab script compute integrals using trapezoidal method. script uses loop , friend told me i'm doing wrong if use loop in matlab. there way convert script matlab-friendly one? 

%number of points use n = 4;  %integration interval = 0; b = 0.5;  %width of integration segments h = (b-a) / n;   f = exp(a); = 1:n-1     f = f + 2*exp(a+i*h); end f = f + exp(b); f = h/2*f

vectorization important speed , clarity, using built-in functions whenever possible. matlab has built in function trapezoidal numerical integration called trapz. here example.

x = 0:.125:.5 y = exp(x) f = trapz(x,y)

SPSS keyboard combination alters encoding -

my question not have programming practical issue on spss. accident keyword combination cannot remember because did not intend press changed encoding in spss , text in data in different language english shown small boxes. nevertheless, when kind of analysis performed different language text shown in output. does know reason? tried change encoding did not produce result. first, @ edit > options , see whether setting unicode or locale. might fix it. if have text in multiple languages, want unicode. otherwise, may have specific locale set wrong. can change set locale, need know locale want use.

javascript - jQuery .height() return 0 when visible but non-0 when hidden -

i have problem here right opposite others: in jquery cannot height of element when it's visible, when hidden. have html code: <div id="filtering-filter-holder"> <div id="filtering-filter-holder-inner"></div> </div> basic css it: #filtering-filter-holder { display: none; position: absolute; width: 420px; min-height: 100px; padding: 5px 5px 5px 5px; background-color: #ffffff; border: 1px solid #164372; } and finally, js in document.ready(): $('div.filtering-filter-headline').mouseenter(function() { var el = $(this).parent().find('div.filtering-filter-content'); if ($('div#filtering-filter-holder').is(':visible')) { $('div#filtering-filter-holder-inner').stop(true, true).fadeout(300, function() { $('div#filtering-filter-holder-inner').html($(el).html()); var height = $('div#filtering-filter-holder-inner&#
