reshape/squeeze for structs?

David Doria — Sun, 30 Sep 2007 17:15:26 -0400

I simply want to count the number of 1's in a specific field
of a struct, like this

a(1).yesno=1;
a(2).yesno=1;
a(3).yesno=0;

if i lookat

a.yesno

i see there are two 1's and one 0.

how can i put these into a vector so i dont have to count in
a loop? Reshape and Squeeze are giving me grief because
this is a struct.

Thanks,

David
