matlab - integrate velocity over depth -

-

i have velocity measurements in 23 layers of water column.

the dz of each layer 1meter.

how can calculate integrated velocity on depth?

is trapz(velocity)/23 ?

many thanks

ah yes, fluid dynamics class. remember well... think best representation of fluid flow given measurements? i'd take first shot @ using microsoft excel, right higher order analysis provide more 'accurate' results.

the 'average' velocity integral (area under curve) in case divided number of equally spaced readings.

trapz fine. there other matlab functions out there, check out

and hey, while we're on topic.. here's next question. happens if measurements aren't uniformly spaced? (hint: draw data on graph paper first... x axis = depth, y axis = velocity)

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.
