I am trying to detect if there is more than one true in the same column of a matrix:
A=[1 0 0; 1 0 0]
r= sum(A,2);
check=sum(r>1)
if check ==0
out= 'single';
else
out='multiple';
but it does not work I do not understand why? And to achieve the same for columns I have used:
col= sum(A);
check=sum(col>1)
if check ==0
out= 'single'
else
out='multiple'
this seems to work for columns.
Is there a better way to check separately if there are multiple true in rows and columns?

Hint:
>> A=[1 0 0; 1 0 1]
A =
1 0 0
1 0 1
>> B = A==1
B =
1 0 0
1 0 1
>> sum( B, 1 )
ans =
2 0 1
>> sum( B, 2 )
ans =
1
2
>>
with A(end,end)==1
