find a row with -1

1 vue (au cours des 30 derniers jours)

Light le 7 Juin 2013

A=[-1,1,1;0,-1,0;0,0,-1;1,0,0];

blnA = logical( A == -1 );

blnOut = find( sum( blnA' ) == 1 );

With that command

blnOut =

1 2 3

I have to find row which include only one -1 or other element in row must be 0 not 1. In that matrix, row including 1 is found too.

So 2nd row must be chosen.

Thank you

blnOut = find(all(ismember(A,[0,-1]),2));
