excel - writetable replace NaN with blanks in Matlab -


given matlab table contains many nan, how can write table excel or csv files nan replaced blanks?

i use following function:

t = table(nan(5,2),'variablenames',{'a','c'})  writetable(t, filename)

i not want replace zeros. want output file:

  1. has blanks nan ,
  2. that variable names included in output.

you need xlswrite that. replaces nans blanks itself. use table2cell or combination of table2array , num2cell convert table cell array first. use variablenames property of table retrieve variable names , pad them cell array.

data= [t.properties.variablenames; table2cell(t)]; %or data= [t.properties.variablenames; num2cell(table2array(t))]; xlswrite('output',data);

sample run for:

t = table([1;2;3],[nan; 410; 6],[31; nan; 27],'variablenames',{'one' 'two' 'three'})  t =    3×3 table      1    2    3     ___    ___    _____      1      nan     31       2      410    nan       3        6     27

yields:

output

although above solution simpler in opinion if want use writetable then:

tmp = table2cell(t);             %converting table cell array tmp(isnan(t.variables)) = {[]};  %replacing nan entries [] t = array2table(tmp,'variablenames',t.properties.variablenames); %converting table writetable(t,'output.csv');      %writing csv file

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 ...
