MATLAB: Convertting from char or double to hex

conversion

Hi, i have a vector which is zeros and ones say A=[1 0 1 0 0 0 1 0] its type is double and i want to convert it to hexadecimal representation i,e the result would be : A2

Best Answer

hextable = '0123456789ABCD';
hextable( A(1:4:end) * 8 + A(2:4:end) * 4 + A(3:4:end) * 2 + A(4:4:end) + 1 )

You can use BITXOR,

V = uint16( round(65535*rand(5,1)) );
V2 = bitxor(V,1+2+4); % 1+2+4 = 7 = 0000000000000111
dec2bin(V)
dec2bin(V2)

MATLAB: Convert binary string into hex

lookup = containers.Map(cellstr(dec2bin(0:15,4)),cellstr(dec2hex(0:15)));
binary_string = '0101010011101010';
output = cellfun(@(S) lookup(S), cellstr(reshape(binary_string, 4, []).')).';

This code assumes that binary_string is a multiple of 4 bits.

This is definitely not the only way to do the task. It has the advantage, though, that it does not need to convert the inputs into numeric form.

Another way:

output = cell2mat(regexprep(cellstr(reshape(binary_string,4,[]).'), cellstr(dec2bin(0:15,4)), cellstr(dec2hex(0:15)),'once').');
