random - Does the rand function ever produce values of 0 or 1 in MATLAB/Octave? -


i'm looking function generate random values between 0 , 1, inclusive. have generated 120,000 random values using rand() function in octave, haven't once got values 0 or 1 output. rand() ever produce such values? if not, there other function can use achieve desired result?

if read documentation of rand in both octave , matlab, open interval between (0,1), no, shouldn't generate numbers 0 or 1.

however, can perhaps generate set of random integers, normalize values lie between [0,1]. perhaps use randi (matlab docs, octave docs) generates integer values 1 given maximum. this, define maximum number, subtract 1 , divide offset maximum values between [0,1] inclusive:

max_num = 10000; %// define maximum number n = 1000; %// define size of vector out = (randi(max_num, n, 1) - 1) / (max_num - 1); %// output

if want act more rand including 0 , 1, make max_num variable quite large.

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 ...
