I have "d879c14e5b1fa7a413aa46bbbc2b8710" this in char form and I want to convert this into string. As i want to split 2-2 character into binary so i want to split it into string.

>> str = 'd879c14e5b1fa7a413aa46bbbc2b8710';
>> dec2bin(sscanf(str,'%2x'))
ans =
11011000
01111001
11000001
01001110
01011011
00011111
10100111
10100100
00010011
10101010
01000110
10111011
10111100

"If i want to store each 8 bit binary into an array..."

It is already in a character array.

"...and then convert into decimal number between 0-255, how can i do this?"

Either get rid of the dec2bin:

>> sscanf(str,'%2x')
ans =
   216
   121
   193
    78
    91
    31
   167
   164
    19
   170
    70
   187
   188
    43
   135
    16
    

Or use bin2dec on the character array.
