Combining elements in an array

Hi, I have a logical array, A = [1 0 1]. How can I combine the elements horizontally, so that I have B = [101]? Any help would be appreciated! SS

To turn your logical array into a double array, any mathematical operation on it will do the conversion. Here I used ‘+’:

A = logical([1 0 1])
An = +A
whos A*

A =

       1     0     1

An =

       1     0     1

    Name      Size            Bytes  Class      Attributes

    A         1x3                 3  logical              
    An        1x3                24  double

Assuming you intend to combine the individual digits into a single decimal number:

B = sum(A.*(10.^(numel(A)-1:-1:0)));

If you intended to make a string instead, then

B = char(A+'0');
