python - Resize/stretch 2d histogram in matplotlib with x-y dependent number of bins? -

-

i making 2d histogram follows:

import matplotlib plt import numpy np  hist,xedges,yedges = np.histogram2d(x,y,bins=[50,150],range=[[0,50],[0,150]]) hmasked = np.ma.masked_where(hist==0,hist) # mask pixels value of 0 extent = [xedges[0], xedges[-1], yedges[0], yedges[-1] ] plt.imshow(hmasked.t,extent=extent,interpolation='nearest',origin='lower') plt.show()

this has 50 bins in x , 150 bins in y. resulting plot narrow in x , tall in y. how stretch out plot in x bins in x allowed appear wider? if there code automatically stretches normal figure aspect ratio, optimal.

plt.imshow(hmasked.t,extent=extent,interpolation='nearest',origin='lower', aspect='auto')

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.
