I have a char array like this '10000111101010110101' and I want to convert each 0 and 1 to int and obtain [1 0 0 0 0 1 1 ...]. I'd like to do it without fors, is it possible?

Easy peasy
x = '10000111101010110101';
y = x - '0'

If you look at the ASCII code for the character, you can see what is happening.
For example,
x = '10000111101010110101';
y = x + 0
Result
>> y
y =
Columns 1 through 17
49 48 48 48 48 49 49 49 49 48 49 48 49 48 49 49 48
Columns 18 through 20
49 48 49
So, if you subtract the ascii code for '0', you will get actual numbers.
