I have used the following code,but the value of count is not changing.
St='010101';
count=0;
a=0;
for i=1:6
a=St(i);
if(a==1)
count=count+1;
end
end

S='010101'
out=nnz(S-'0')
To correct your for loop
St='010101';
count=0;
a=0;
for i=1:6
a=St(i);
if(a=='1')
count=count+1;
end
end

This seems to work:
St='010101';
count=0;
a=0;
for i=1:6
a=St(1,i);
if(str2num(a)==1)
count=count+1;
end
end
