convert 16bit char to 4 byte hex values

I have an length X 16 variable of type char. i'd like to convert it to length x 4 nibble hex values

example input: char(3x16)

1000100010001000

0000000000000010

111111111111111111

output wanted 8888

0002

FFFF

c=char(["1000100010001000";
"0000000000000010";
"1111111111111111"])

c = 3×16 char array
    '1000100010001000'
    '0000000000000010'
    '1111111111111111'

d=dec2hex(bin2dec(c))

d = 3×4 char array
    '8888'
    '0002'
    'FFFF'

Very nice and simple! thank you. i have been trying every conversion function in the book and thought it would take a double to work.

I thought there should be a bin2hex() function but didn't find it. Maybe someone else can suggest a direct conversion method?

If your original data is not constrained to be char array, maybe take a look at this document

There is a custom bin2hex()-function on File Exchange
