matlab - Good way to get phase difference between vectors? -


so have 2 vectors:

>> [phase exp_phase]  ans =      0.2266         0    -0.0702         0    -0.0070         0    -0.0854         0     0.0888         0     3.1403   -3.1416    -2.9571   -3.1416    -0.1441         0    -0.2660         0     2.8749   -3.1416     0.0126         0    -2.9309   -3.1416     0.0064         0

phase obtained atan2(b,a). want figure out phase difference. problem want difference between -3.00 , +3.00 0.28, @ same time want difference between -2.72 , +3.00 same.

it's trivial can't figure out way :(

say have 2 angles, w1=+3 , w2=-3 (both in radians). find smallest angular difference, following:

atan2(sin(w1-w2),cos(w1-w2))  ans =     -0.2832

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
