binary to ascii converting

Hi, how can I convert a 96 bit binary string to the 8-bit ascii? I should find a sentence

Try this:

binstr = char(randi([0 1]+'0', 1, 96));                 % Create (Random) Binary Character Vector
binstr8 = reshape(binstr, [], 8);                       % Reshape To (12x8) Character Array
binmtx = bin2dec(binstr8);                              % Convert Binary Character Array To Decimal Column Vector
chrmtx = char(binmtx);                                  % Convert Decimal Column Vector To Character Column Vector

You can combine these into one line if you want to. I kept them separate to demonstrate how the code works.

chrmtx = @(x) char(bin2dec(reshape(x(:).',[],8)));      % One-Line Anonymous Function Version Of This Code
Out = chrmtx(binstr);

thank you for helping ,

this is my answer for a question and I should change this to the ascii 8bit text

result = "010010010111001101101110001001110111010000100000011100000111001001101111011000100110000101100010011010010110110001101001011101000111100100100000011001110111001001100101011000010111010000111111"

I couldnt find answer with your code

binstr = '010010010111001101101110001001110111010000100000011100000111001001101111011000100110000101100010011010010110110001101001011101000111100100100000011001110111001001100101011000010111010000111111'
% binstr = char(randi([0 1]+'0', 1, 96));                 % Create (Random) Binary Character Vector
binstr8 = reshape(binstr, [], 8)  % Reshape To (12x8) Character Array
binmtx = bin2dec(binstr8)         % Convert Binary Character Array To Decimal Column Vector
chrmtx = char(binmtx)             % Convert Decimal Column Vector To Character Column Vector

Worked for me. What did you do differently?

[Star Strider]

One change to ‘binstr8’:

binstr8 = reshape(binstr(:), 8, []).';                  % Reshape To (12x8) Character Array

and one change to ‘Out’:

Out = char(binmtx).'                                    % Convert Decimal Column Vector To Character Column Vector

produces:

Out =
    'Isn't probability great?'

Similar changes to the ‘chrmtx’ function:

chrmtx = @(x) char(bin2dec(reshape(x(:),8,[]).')).';
Out = chrmtx(binstr)

produces the same output.

Error using reshape

Product of known dimensions, 8, not divisible into total number of elements, 1.

and binstr8 gives me 24x8 matrix

[Walter Roberson]

Is your x a character vector, or is it a string() object? When you display it, does it show up surrounded by ' quotes such as 'abc' or does it show up surrounded by " quotes like "abc" ?

@homa maleki —

Change ‘binstr8’ to:

binstr8 = reshape(char(binstr(:)), 8, []).';            % Reshape To (12x8) Character Array

and:

chrmtx = @(x) char(bin2dec(reshape(char(x(:)),8,[]).')).';  % One-Line Anonymous Function Version Of This Code

This illustrates the problem of not having your data to work with at the outset.

[homa maleki]

its by "quotes

[Star Strider]

That means it is a string array, not a char array.

The changes in my code should now accommodate both.

Thank you so much it is working now

[Star Strider]

My pleasure.
