Please how can we efficiently calculate the hamming-weight of a bit-string in elixir? Example: 0b0101101001 has a Hamming-weight of 5 (i.e. 5 bits set) My Attempt: iex> Enum.count(Integer.to_...

How do I get pandas to append an integer and keep the integer data type? I realize I can df.test.astype(int) to the entire column after I have put in the data but if I can do it at the time I'm app...

Is there a shortcut to Convert binary (0|1) numpy array to integer or binary-string ? F.e. b = np.array([0,0,0,0,0,1,0,1]) => b is 5 np.packbits(b) works but only for 8 bit values ..if the...

I have a pandas Dataframe containing 1 columns which contains a string of bits eg.'100100101'. i want to convert this string into an numpy array. How can I do that? EDIT: Using features = df.bi...

Is there a way to split a bitstring loaded from a file on newlines? I have something like this: A line of text Additional line of text And another line And I want an array like this: ["A line o...

In the Erlang shell, I can do the following: A = 300. 300 <<A:32>>. <<0, 0, 1, 44>> But when I try the following: B = term_to_binary({300}). <<131,104,1,98,0,0,...

I am working on a Python library that performs a lot of bitwise operations on long bit strings, and I want to find a bit string type that will maximize its speed. I have tried the built-in Python i...

Given a MATLAB uint32 to be interpreted as a bit string, what is an efficient and concise way of counting how many nonzero bits are in the string? I have a working, naive approach which loops ove...

Does Elixir have a function that accepts integers and floats and converts them to strings? I need something like this: a = 3 b = 3.14 number_to_binary(a) % => "3" number_to_binary(b) % => "...

I have a 160 chars bit string and I need to have an integer array that stores the position of the bits that have a value of 1. Example: bitstring = '00110101' array = [3,4,6,8] Is it possible t...

How do you concatenate bitstrings. I mean bitstrings because I do not know the number of bytes to be a multiple of 8. A = <<3:2>> B = <<1:1>> C = <<15:4>> Solu...

I want to read as many 24 bit chunks as possible from a file. How can I do this using bitstrings' ConstBitStream when I don't now how many chunks there are? Currently I do this: eventList = Const...

I'm writing a simulation in Matlab. I will eventually run this simulation hundreds of times. In each simulation run, there are millions of simulation cycles. In each of these cycles, I calculate a ...

I'm writing code to decode messages from a binary protocol. Each message type is assigned a 1 byte type identifier and each message carries this type id. Messages all start with a common header con...
