imagine you have a two matrixes:
a=[1 2 3 4 5 6 7 8 9];b=[1 0 1 0 1];
how do i use the b matrix as a logical index? I'd expect:
a(b)ans =[1 3 5]
but instead i get the error: "Subscript indices must either be real positive integers or logicals."
if I try a(~b) ans =[2 4]
now I could use a(~~b) which does what i want but this seems inelegant. Can anyone suggest a better solution?
