Looking at the second return value of max(a,[],2) is a way to find the index
of the first true element in each row of a.

matlab supports this when a is sparse logical, but octave gives an error:

octave:7> [i,j] = max(logical(speye(3)),[],2);
error: octave_base_value::int8_array_value(): wrong type argument 'sparse bool

Of course you can always just convert the argument to double
