p=4 and b1=dec2bin(p,8) now b1='00000100' and iwant now b1= 0000 first raw & 01000 second raw 2*4 size matrix from binary digit number

8 digit binary to 4 digit group and make matrix from it b1= 0 0 0 0(first raw) 0 0 0 1(second raw) b2= 0 0 0 0 1 0 1 0 2*4 size matrix

Answer 1

[KSSV]

b = '00000001' ;
B = b - '0' ;
iwant = reshape(B,2,4)

[Pratik Anandpara]

direct consider with dec2bin answer than create this error 'Undefined function 'minus' for input arguments of type 'cell'. it is not array its direct answer of command 'dec2bin'

[KSSV]

Copy your code, what you have done.

[Pratik Anandpara]

p1=4

p1 =

     4

>> dec2bin(p1,8)

ans =

00000100

>> b = p1; B = b - '0' ; iwant = reshape(B,2,4) Error using reshape To RESHAPE the number of elements must not change.

[Pratik Anandpara]

reshape(dec2bin(6,8)-'0',4,2).' i also try this but this is valid for some digit if we do for reshape(dec2bin(4,8)-'0',4,2).' than answer is correct

[KSSV]

p1 = 4 ;
b = num2str(dec2bin(p1,8));
B = b - '0' ;
iwant = reshape(B,2,4)
