what kind of "vector" is this?

[Muhammad Tanveer]

hexadecimal values...... is it possible to get the string like 68656c6c6f20686f? i want to convert this string into a matrix of 4*4.

[Muhammad Tanveer]

str = sprintf('%d', mtx) out put in decimal form input=4f 6c 01 61 4d 1f 64 07 output=7910819777311007 but i want 4f6c01614d1f6407

Can you use valid syntax for showing your input. It is not possible to have the literal vector [68 65 6c 6c 6f 20 68 6f] in matlab.

Please show a valid input example and corresponding desired output.

[Muhammad Tanveer]

clc
 format hex
str=input('Enter the key of sixteen alphabets in uper or lowercase  case leteers==');
decString = unicode2native(str,'utf-8')
decString =

   68   65   6c   6c   6f   20   68   6f   77   20   61   72   65   20   79   6f

All you changed with format hex is the way Matlab shows you the values, you didn't actually change the values. You can convert the decimal values to a hex string, and then concatenate the strings. What you end up with is a 1x32 char vector, which you could reshape into a matrix if you like.

decString=[104,101,108,108,111,32,104,111,119,32,97,114,101,32,121,111];
str=dec2hex(decString(:))';str=str(:)';
