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');
