Binary string to character string?

Hello Sir!

There is an binary string 'watermark', like this:

watermark =

00000000000000000000111111110111111000001111111111111111111100001000010010000000001001001001011111110011001110001010000010101100110100011111010100110011011000000000000000000000000000000000000000000000111111111111111111111111111110000000000000000001111111111111000111100000000000000110011001111111111110101010100000000000

whos watermark
  Name            Size                   Bytes  Class

    watermark       1x320                    640  char array
Grand total is 320 elements using 640 bytes

I want to convert it into character string. The expected string is :

banerjee.raktim*****123456789***********

I wrote this:

>> char(bin2dec(watermark))
??? Error using ==> bin2dec
Binary string must be 52 bits or less.

How to do this?

Answer 1

[Matt Fig]

userid = char(bin2dec(reshape(watermark(1:160),[],8))).'
passwrd = char(bin2dec(reshape(watermark(161:320),[],8))).'
str = [userid passwrd]

Thank You Sir a lot! It works.

This duplicates a question in #349

Not quite. This duplicates a question asked in the comments section of question #349. If the OP had been thinking thoroughly, he could have asked for a solution AND its inverse.
