Converting a dynamically sized mxArray to struct in Matlab Simulink -


i have extrinsic function returns mxarray through webread(). mxarray should struct, can access , read data in it. problem has dynamic size, can't define it's size statically.

this code:

function out = getdatafromcloud() coder.extrinsic('webread'); coder.extrinsic('weboptions');  url = 'theurl'; options = weboptions('contenttype','json'); data_conv = webread(url); disp(data_conv(1:1).code); %at point fails, because '.code' not  %possible mxarray

i'm quite new matlab please gracious. thank every answer can give!

edit1

i created dummy data, can test problem yourself. dummy data link. explanation: in dummy data, amount of category_0 3, there's code, subcat_0 , subcat_1. within those, there variables static, variables hold dynamically filled arrays.

the code above enables needed reproduce error. use getdatafromcloud() in matlab simulink model this.

model block

what necessary well, change 'theurl' url provided. code doesn't need changing , should reproduce problem. if not, write comment.

edit2

by now, i've figured out way of wanted matlab s-function. if you're interested, created repo it. question still stands though, i'd love hear answer it.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
