matrix - Plot the Centroid of a Dataset in Matlab -


in matlab have painted figure x1,y1,z1 axis using 

h=plot3(x1,y1,z1,'y*');

and x1,y1 , z1 row matrix shape. want highlight point (x,y,z) consisting of average of each row matrix in same figure. how highlight average point in sharp or color , avoid being covered row matrix point. want source program matlab plot3().

so want highlight centroid of cluster. can following code.

x1 = rand(10,1); y1 = rand(10,1); z1 = rand(10,1);  plot3( x1, y1, z1, 'y*' ); hold on; scatter3( mean( x1 ), mean( y1 ), mean( z1 ), 'r' ); hold off;

you can use scatter3 plot point in red using 'r' parameter. circles best job , won't covered hollow. can use different colors or markers built matlab.

here results

unless you're plotting trajectory, if plotting points, suggest use scatter3 instead of plot3. gives following plot.

i suggest using blue instead of yellow better visibility.

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 ...
