how to split a string (char value) with zero in front of it but showing the value in the matrix?

I have a string of '0100'. i want to split it into binary bit 0 1 0 0. how can i do that?? whenever i turn it into double or integer it turns out 1 0 0,

Answer 1

[Stephen23]

S = '0100';
V = sscanf(S,'%1u')

V = 4×1

0 1 0 0

MATLAB does NOT allow you to store or represent an integer as the number 0100. If you try, you will get 100. The leading zero goes away. I'm sorry, but it does, and nothing will make that change.

Your simple solution is to NOT convert it into a number. Work with it in terms of strings. Or if you prefer, as a vector of booleans, so 0 or 1 elements.

For example, could you search for leading zeros, counting how many? Yes.

Two more ways:

S = '0100';
S=='0' % logical result

ans = 1×4 logical array
   1   0   1   1

S-'0' % double result

ans = 1×4

0 1 0 0
