xcode5 - Compiling embedded MATLAB functions in Simulink, Mac OSX 10.9 Mavericks, Xcode 5, MATLAB 2012b -


after updated latest osx mavericks, i've had issues compiling simple matlab function blocks in simulink, diagram , attached code below. simple simulink diagram 

function y = fcn(t)    %#codegen    %simple matlab .m function compiled diagram  y = sin(t)+cos(t);

i had same problem under osx 10.8 mountain lion, able solve problem downloading mathworks patch , following instructions on this site.

with new os , having upgraded xcode 5, followed instructions in this post change compiler , sdk info in mexopts.sh file from

#patch: macosx10.8         cc='llvm-gcc-4.2'         cxx='llvm-g++-4.2'         sdkroot='/applications/xcode.app/contents/developer/platforms/macosx.platform/developer/sdks/macosx10.8.sdk/'          macosx_deployment_target='10.8'         archs='x86_64'

to

#patch: macosx10.9         cc='llvm-gcc'         cxx='llvm-g++'         sdkroot='/applications/xcode.app/contents/developer/platforms/macosx.platform/developer/sdks/macosx10.9.sdk/'          macosx_deployment_target='10.9'         archs='x86_64'

after running mex -setupand restarting matlab, following error when trying run simulink model function block (the behavior same models these blocks):

making simulation target "mextest_sfun", ...    /applications/matlab.app/bin/mex -c -o   -dmatlab_mex_file  -i/applications/matlab.app/toolbox/stateflow/stateflow/../../../simulink/include  -i/applications/matlab.app/toolbox/stateflow/stateflow/../../../extern/include  -i/applications/matlab.app/stateflow/c/mex/include  -i/applications/matlab.app/stateflow/c/debugger/include   mextest_sfun.c clang: warning: treating 'c' input 'c++' when in c++ mode, behavior deprecated  /applications/matlab.app/bin/mex -c -o   -dmatlab_mex_file  -i/applications/matlab.app/toolbox/stateflow/stateflow/../../../simulink/include  -i/applications/matlab.app/toolbox/stateflow/stateflow/../../../extern/include  -i/applications/matlab.app/stateflow/c/mex/include  -i/applications/matlab.app/stateflow/c/debugger/include   mextest_sfun_registry.c clang: warning: treating 'c' input 'c++' when in c++ mode, behavior deprecated  /applications/matlab.app/bin/mex -c -o   -dmatlab_mex_file  -i/applications/matlab.app/toolbox/stateflow/stateflow/../../../simulink/include  -i/applications/matlab.app/toolbox/stateflow/stateflow/../../../extern/include  -i/applications/matlab.app/stateflow/c/mex/include  -i/applications/matlab.app/stateflow/c/debugger/include   c2_mextest.c clang: warning: treating 'c' input 'c++' when in c++ mode, behavior deprecated  /applications/matlab.app/bin/mex -silent ldflags="\$ldflags " -output mextest_sfun.mexmaci64      mextest_sfun.o mextest_sfun_registry.o c2_mextest.o      /applications/matlab.app/stateflow/c/mex/lib/maci64/sfc_mex.a /applications/matlab.app/stateflow/c/debugger/lib/maci64/sfc_debug.a -l/applications/matlab.app/bin/maci64 -lfixedpoint -lut -lmwmathutil -lemlrt -lmwblascompat32  -l/applications/matlab.app/bin/maci64 -lippmwipt undefined symbols architecture x86_64:   "sf_debug_api(int, mxarray_tag**, int, mxarray_tag const**)", referenced from:   _mexfunction in mextest_sfun_registry.o "_callcustomfcn", referenced from:   _mdl_start_processing in sfc_mex.a(sfc_sf.o)   _mdlterminate in sfc_mex.a(sfc_sf.o) "_sf_machine_global_initializer", referenced from:   _mdl_start_processing in sfc_mex.a(sfc_sf.o)  "_sf_machine_global_method_dispatcher", referenced from:   _call_sf_machine_global_method_dispatcher in sfc_mex.a(sfc_sf.o) "_sf_machine_global_terminator", referenced from:   _mdlterminate in sfc_mex.a(sfc_sf.o) ld: symbol(s) not found architecture x86_64 clang: error: linker command failed exit code 1 (use -v see invocation)  mex: link of ' "mextest_sfun.mexmaci64"' failed.  gmake: *** [mextest_sfun.mexmaci64] error 1

i'm thinking it's undefined symbols architecture x86_64 key message here, not know. have had same issues, or have solution this? appreciated. thanks!

after searching internet , waiting answers on forum no results, solution problem became upgrading matlab 2013a.

in addition, little modification mexopts.shfile needed. replace instances of 10.7 either 10.8 or 10.9. both of these worked me, ended replacing 10.9 i'm running mavericks.

the "official" solution can found on this site.

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

first of all, thank being patient know simple question more couple of weeks' experience figure out. i've seen folks persevere , helpful on here , hope you're willing me. here fiddle: http://jsfiddle.net/65uzf/ here 1 of places searched answers on here: ( vertically center image thumbnails fix-sized div ) tried solutions on there , didn't work out me. i've searched ~4 or 5 others, , been unsuccessful those, too. what want take large image (what linked background-image #ysypic , #tabpic divs) , display thumbnail version of image in confines of divs have set it. is, using background properties have laid out in css, portion of image displays inside of circular divs. without these properties, display defaults smaller section of image [presumably pi*(50^2) area in top left] terrible resolution. i not care if entire image doesn't display inside of circles (it won't, given difference in shape), , overflow not being displayed fine. want able see figu

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
