function T=any(s)
//ANY    True if any element of a vector is nonzero.
//   For vectors, ANY(V) returns 1 if any of the elements of the
//   vector are non-zero. Otherwise it returns 0. For matrices,
//   ANY(X) operates on the columns of X, returning a row vector
//   of 1's and 0's. For N-D arrays, ANY(X) operates on the first
//   non-singleton dimension.
//
//   ANY(X,DIM) works down the dimension DIM.  For example, ANY(X,1)
//   works down the first dimension (the rows) of X.
