matlab - GUI won't run correct unless radio buttons are cycled through -


i've created gui estimates materials , pricing involved in building home given few criteria provided in ui panels radio buttons options. problem hitting go button gui throws errors unless radio buttons played first. cannot leave buttons on selection when gui run. how can run .m file , hit go on .fig without having touch (aside filling in square footage edit box)?

 function uibuttongroup3_selectionchangedfcn(hobject, eventdata, handles)     % hobject    handle selected object in uibuttongroup3      % eventdata  reserved - defined in future version of matlab     % handles    structure handles , user data (see guidata) tag = eventdata.newvalue; switch get(tag,'tag') case 'onehalfbath'     bathroom = 1 case 'twohalfbath'     bathroom = 2 case 'threehalfbath'     bathroom = 3 end; if bathroom == 1     bathwall = 30     bathsq = 36 elseif bathroom == 2     bathwall = 48     bathsq = 72     elseif bathroom == 3     bathwall = 66     bathsq = 108 end; setappdata(handles.uibuttongroup3,'bathwall',bathwall); setappdata(handles.uibuttongroup3,'bathsq',bathsq); setappdata(handles.uibuttongroup3,'bathroom',bathroom);

the above 1 of 4 ui panels radio buttons, example. written same way. snippets of go button callback below.

function gobut_callback(hobject, eventdata, handles) % hobject    handle gobut (see gcbo) % eventdata  reserved - defined in future version of matlab % handles    structure handles , user data (see guidata) run('urlprice.m'); bathroom = getappdata(handles.uibuttongroup3,'bathroom'); bathsq = getappdata(handles.uibuttongroup3,'bathsq'); bathwall = getappdata(handles.uibuttongroup3,'bathwall'); % floor = get(handles.floor,'value') homename = get(handles.homename,'string');  base = get(handles.basesqft, 'string'); basesqft = str2num(base);  totsqft = basesqft .* floor;   perim = (((basesqft .^ .5) .* 4) .* floor); perim2 = (basesqft .^ .5) .*4; perim3 = (basesqft .^ .5);  walllnft_01 = perim + (bedwall .* 2) + (bathwall .* 2); % double side wall walllnft_02 = perim + bedwall + bathwall; % 1 side wall  intdoor = (bedroom .* 2) + (bathroom) + 2;  tile = ceil(bathsq/17.44287);  thinset = bathroom + 1;   index of element remove exceeds matrix dimensions.

the error messages:

index of element remove exceeds matrix dimensions.  error in cur2str (line 75) t(1,:) = [];  error in homebuilding>gobut_callback (line 267) estmat = cur2str(estmat1,2);  error in gui_mainfcn (line 95)     feval(varargin{:});  error in homebuilding (line 42) gui_mainfcn(gui_state, varargin{:});  error in       @(hobject,eventdata)homebuilding('gobut_callback',hobject,eventdata,guidata(hobject))   error while evaluating uicontrol callback

you use setappdata store variables later use in uibuttongroup3_selectionchangedfcn. problem done in function. means the variables not stored until uibuttongroup3_selectionchangedfcn called, happens when radio buttons played said.
when gui opens, variables not defined yet. therefore should define 3 variables in openingfcn default value, or make sure user set buttons before hitting go.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
