i have 73 x 1 cell, each of cells contains 16 x 1 cell , each of cells image. there easy way can convert 1 big array of cells containing images? many thanks. if c cell, use b = [c{:}] create 16×73 cell b every column 1 of original 16×1 cell elements. works, because c{:} accesses every element in cell c , brackets ( [ ] ) group these elements 1 array again. possible, because every element in c of same type , size. use b = b(:) 1168×1 cell (73*16=1168), if want. either way, b{n} accesses n -th image.

i'm writing gem acts client remote api, i'm using webmock mock out remote api, testing cucumber rspec-mock present too. as part of cucumber tests intend stub api in given clause specify remote api called in then clause. a basic example be: feature file scenario: doing triggers call given have mocked google when call library calls google stub , response library step definition given /i have mocked api/ stub_request(:get, 'www.google.com') end when /i call library/ mylibrary.call_google_for_some_reason end /it calls google stub/ # somehow test here end the question: how can verify google stub has been called? side note: i'm aware use expect(a_request(...)) or expect(webmock).to ... syntax feeling i'll repeating what's defined in given clause. i answer myself, though verify correct and/or has no major pitfalls: given /i have mocked api/ @request = stub_request(:get, 'www.google.com') end /it calls

let assume have expression in latex form: var latex =\frac{x}{\frac{y}{y}} so output required is: output= (x)/((y)/(y)); i tried out example stated in link: convert latex dynamic javascript function getting output of above latex as: (x)/(\frac{y){y}}` how can expression converted properly? in advance! solution of above problem var func = '\frac{x}{\frac{y}{y}}'; func = func.replace(/}{/g, ")/(").replace(/\frac{/g, "(").replace(/}/g, ")") console.log(func); innput = \frac{x}{\frac{y}{y}} output = (x)/((y)/(y))

i have java gui have written, has underlying end in matlab. i trying call end functions java portion ease of use, , have been able run matlab functions java using matlab controller ( https://code.google.com/p/matlabcontrol/ ), implementation seems limited numeric data, whereas data dealing array of strings (call 90 x 8 array of strings safe). i able see array of numbers in java using matlabcontroller library. i have tried using matlab compiler sdk , there multiple internally generated errors when tried running code. i out of ideas of how might accomplish conversion. json unreasonable option pursue? i think you're doing wrong way. don't send matlab array java. instead construct java array in matlab, , send java. how done here http://de.mathworks.com/help/matlab/ref/javaarray.html .

i have read thread still faced similar issue: googleapiclient onconnected never called on wearable device i tried follow how works: https://developer.android.com/training/wearables/data-layer/events.html here codes: public class main extends activity implements dataapi.datalistener, googleapiclient.connectioncallbacks, googleapiclient.onconnectionfailedlistener { private static final string path = "/phonewatch"; private googleapiclient client; @override protected void oncreate(bundle savedinstancestate) { log.d("phone watch", "on create!"); super.oncreate(savedinstancestate); setcontentview(r.layout.main); client = new googleapiclient.builder(this).addapi(wearable.api).build(); ... } @override protected void onstart() { log.d("phone watch", "on start!"); super.onstart(); client.connect(); } @override protected void onstop() { log.d("phone watch", "on stop!");
