struct - getting field name as a string in matlab -

-

i have matlab reference manual

value = getfield(struct, 'field')

where struct 1-by-1 structure, returns contents of specified field, equivalent

value = struct.field

how can opposite

getstringname(struct.field) return 'field'

also if possible point @ field in numerical way similar array

like struct{1} field 1 field

edit

if follow

structname(1) list of field names, , dimentions

                speed: [2244x1 double]                  time: [2244x1 double] ... , on

i want grab title speed string, , if possible

structname(1).filed(1) speed without doing structname(1).speed

i want print each field file field name!

so if do

for i=1:sizeofstruct    printtofile(structname(i)); %<=== accessing field index, problem 2 end  function printtofile(structfield)    structfieldstr = getstrfiledname(structfield); %<=== obtain field string, main problem    filename = strcat(fileloc, '/profile/', structfieldstr, '.dat');    %...   open file , dump end

not complete answer question, should started:

s.a = 11; s.b = 22; s.c = 33; names = fieldnames(s); = 1:length(names)     fprintf('field %s = %g\n', names{i}, s.(names{i})) end

result:

field = 11 field b = 22 field c = 33

note syntax programmatically access field name: s.(name), s struct , name string.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
